Aerodynamics plays a crucial role in this, and its optimization can have a significant impact on fuel efficiency. The role of aerodynamic research for transportation is to investigate solutions to improve the aerodynamic performance that minimizes power consumption. The main objective of Guglielmo Minelli&#39;s thesis is, therefore, to reduce drag, controlling the external flow that normally surrounds a road vehicle, by means of &quot;active flow control&quot;.</b></p>​<span style="background-color:initial">Active flow control was shown to be an effective and low energy consumption technique to improve the external aerodynamics of a traveling truck. </span><div><br /></div> <div>“Controlling the flow around a vehicle, one not only minimizes the aerodynamic drag but also improves the comfort of the driver, reducing noise and soiling,” says Guglielmo Minelli.</div> <div><br /></div> <div>He tells that the ambition of Europe is clear: by mid-century, greenhouse gas emissions from transport will need to be at least 60% lower than in 1990 and be firmly on the path towards zero. Emissions of air pollutants from transport that harm our health need to be drastically reduced without delay. </div> <div><br /></div> <div>“Trucks, in particular, need to improve their efficiency to extend their mileage and decrease their power consumption. Thus, improving the aerodynamic features of heavy trucks and road vehicles is a necessary contribution toward the target, and active flow control can play an important role in this” says Guglielmo Minelli.</div> <div><br /></div> <div>The results of his work focus on two main points. First, synthetic jets were shown to be an effective and low energy consumption technique to control a pressure induced separated flow. Both computational fluid dynamics results and wind tunnel experiments demonstrated the efficacy of active flow control by significantly improve the aerodynamic performance of a road vehicle. Second, the computational fluid dynamics hybrid numerical method PANS was shown to be an interesting approach for industrial applications. </div> <div><br /></div> <div>“Its capability to resolve unsteady flow cases preserving the accuracy of the flow structures is shown, even when meshes are relatively coarse.” Says Guglielmo Minelli</div> <div><br /></div> <div>Guglielmo Minelli will defend his thesis “Flow Control for Aerodynamic Drag Reduction of Trucks” <a href="/sv/institutioner/m2/kalendarium/Sidor/Flow-Control-for-Aerodynamic-Drag-Reduction-of-Trucks.aspx">December 8 at 10.00 in lecture hall KB. </a></div> Tue, 05 Dec 2017 14:00:00 +0100 thesis could make a more fuel efficient aircraft possible<p><b>Lowering of fuel consumption and emissions is of paramount importance in the aerospace industry but the aircraft engine is a complex system. The different parts are dependent on each other and it’s difficult to determine which component to take care of first and foremost to make the aircraft engine more efficient. Oskar Thulin deals with this in his PhD thesis ”On the analysis of energy efficient aircraft engines”</b></p><div><div>The aircraft engine consists of many integral components and each component will influence the overall performance of the system. Furthermore, the aircraft engine has weight and contributes to drag that must be compensated for by the engine. Using the regular way to assess performance, it is impossible to compare one component's loss to another or to directly relate an individual component's loss to the overall loss. Oskar Thulin has developed an analytical method that makes it possible to directly compare component losses in a system perspective. The method also makes it possible to include weight or caused drag in the analysis.</div> <div><br /></div> <div>&quot;This gives a much more clear picture of how big the losses are for the various components, as well as for each component type&quot; says Oskar Thulin.</div> <div><br /></div> <div>The developed framework is used to study various aircraft engines. In general, it can be said that the hot exhaust gases that leave the engine, the combustion process in itself, and the part of the kinetic energy in the exhaust that is not used to propel the aircraft forward, are the main sources of the overall loss.</div> <div><br /></div> <div>&quot;Based on the analysis you can discuss different technologies that can do something about these dominant losses.

In Sweden we have long had high-quality maritime education and training, and our sailors have a reputation for competence. Over the past ten years we have also worked hard to further develop and improve the quality of the educational programmes,” says Fredrik Olindersson, Head of the Division for Maritime Studies at Chalmers.</div> <div><br /></div> <div><a href="">The International Association of Maritime Universities (IAMU) </a>, an organisation whose members include more than sixty of the most prominent universities in the field, is behind the study. Chalmers was elected to IAMU in 2016.</div> <div><br /></div> <div>“It took over a year to become a member. You have to send in masses of documents, and they carry out site visits to make sure you live up to their high standards. Not just anyone can join. At the last Annual Meeting a couple of new universities joined, but several also applied and were not accepted,” Olindersson says. </div> <div><br /></div> <div>The study is intended to give IAMU’s member universities an idea of where their strengths lie and what they could develop. So the organisation does not provide traditional rankings but confines itself to listing, in alphabetical order, the universities that fall in the upper quartile (top 25%) in the three areas studied. </div> <div>“Chalmers University of Technology came out top in all the areas studied – global exchange, strength of research and quality of education. What is most striking about the study is that Chalmers is the most well-balanced university. That is Chalmers’ strength and one that should be nurtured and further developed,” says Takeshi Nakazawa, Executive Director of IAMU.</div> <div><br /></div> <div>Olindersson explains that Chalmers is often used as a model for a maritime educational institution around the world and that is why there are so many international visits to Chalmers. </div> <div><br /></div> <div>So what is the strength of maritime education and training in Gothenburg?</div> <div><br /></div> <div>“In addition to having competent teachers, we are one of the few educational institutions which invests a great deal in simulator education and in the work of simulator instructors. We want to maximise the impact of the expensive time spent in the simulator that forms part of the training.”</div> <div><br /></div> <div>According to Olindersson, Chalmers University of Technology is far ahead of most others in the world in its educational work on sustainability and the environment. All maritime training in the world complies with the International Convention on Standards of Training, Certification, and Watchkeeping for Seafarers (STCW) which governs the minimum standards of training, but like other IAMU members, Chalmers offers education and training at a significantly higher level.</div> <div><br /></div> <div>“The Heads of Programmes have continuously extended the programmes and have placed much greater emphasis on leadership, communication, critical thinking, and sustainability. To improve the eligibility of students, and their employability in the long term, we have also introduced a number of elective courses to the programmes. On the Master Mariner programme, students can choose to specialize in passenger and cruise ships, tanker shipping or the offshore sector. The Marine Engineer programme now includes a high voltage element, and there are elective courses in advanced ship operations, marine risks, and marine ergonomics.”</div> <div><br /></div> <div>On the research side, maritime environmental sciences, maritime human factors and marine technology are strong Chalmers areas.

What sets us apart is that many other universities don’t do this. However, we’ve got several exchange agreements that are working well and another couple is under way that will hopefully lead to more exchanges,” Olindersson says.</div> <div><br /></div> <div><strong>Swedish simulator centre for shipping</strong></div> <div>Campus Lindholmen houses <a href="/en/departments/m2/simulator-labs/simulators/Pages/default.aspx">Sweden’s most extensive simulator centre for education and research in shipping</a>.

Recently, he was elected chairman of an international standardization committee working with vibrations. In the committee, he wants to try to influence the standard so that dangerous vibrations can be stopped.</b></p>​<span style="background-color:initial">Vibration damage is the most common occupational disease in Sweden. Every day, 400,000 people work for more than two hours a day with vibrating machines. This causes a large number of chronic damage to the nerves, vessels, muscles and skeletal system. But it doesn’t have to be like this.</span><div><br /></div> <div> - Machines don't need to vibrate and hurt people! There is no physical law that confirms that” says Hans Lindell, who has shown that machines with significantly lower vibrations can be developed.</div> <div><br /></div> <div>With help from research results, it has been possible to rebuild existing machines, such as chisel hammers and nutrunners, to show that it is possible to greatly reduce vibration levels. Two types of vibrations that are attempted to counteract are rotating and translating that goes back and forth. One of the techniques used is called ATVA (Auto Tuning Vibration Absorber) and is based on vibration reductions by counteracting the forces that cause the vibrations. Prototypes are currently being tested in the field with satisfactory results. Recently, the project was also awarded additional funds from Vinnova to scale up the project and introduce prototypes in vibration-free, industrial demonstration environments in full production.</div> <div><br /></div> <div>Hans Lindell thinks that his extensive experience in the field was the reason for him being elected as chairman of the International Standardization Committee named ISO/TC108/SC4/WG3. One of the standards under the group's responsibility is ISO 5349, which states how to measure and assess the risks of vibrations on handheld tools. Hans Lindell thinks that it feels both nervous and at the same time very fun to get the presidency.</div> <div><br /></div> <div>- There is a great need for an adjustment of the current standard so that it also takes into account machines with impacts and shocks that give high frequency vibration which we suspect cause a large part of the damage. As a chairman, you will be able to drive a change&quot; says Hans Lindell.</div> <div><br /></div> <div>A lot of things are already about to happen thanks to Hans Lindell's research. Machines, where the high-frequency vibration is remedied, will be released on the market within one year. As far as ATVA technology is concerned, it probably takes a few years, but future users will get fewer injuries, machine manufacturers get an opportunity to increase their competitiveness and society earns on reduced costs for a disease. However, there is much more to be found in the vibration area. The ATVA technology is applicable to considerably more uses than handheld machines. There is a lot of applications where vibrations need to be reduced.</div> <div><br /></div> <div> - What's so funny is that the deeper you get into a problem, the more unanswered questions are found&quot; says Hans Lindell</div> <div><br /></div> Thu, 23 Nov 2017 14:00:00 +0100 autonomous and eco-friendly public transportation into cities<p><b>Sohjoa Baltic is a EU-funded project that aims to facilitate the transition to autonomous and eco-friendly public transport in the cities around the Baltic Sea.

Like many other fluids, engine oil becomes thicker at low temperatures. This also leads to a significant increase of the unwanted engine friction and makes the engine consume more fuel when cold. Thermal engine encapsulation is a combination of shells, mounted around the engine, that insulate it from the cold environment and keep it warm for a long time after we turn it off. This way it is more likely that the engine will be warm and efficient next time we start it. </div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial">To design an engine encapsulation is a complex engineering task, which requires knowledge of the energy transport through the entire powertrain of the vehicle.

But while the topic is widely discussed on land, food waste generated on ships seems not to receive similar attention. In her thesis, “Management of ship-generated food waste – illustrated from the Baltic Sea perspective”, PhD Magda Wilewska-Bien, at Chalmers, analyses current management of ship-generated food waste in the Baltic Sea region and discuss effective solutions.</b></p>​<img src="/SiteCollectionImages/Institutioner/SMT/Profilbilder/Wilewska-Bien-M.jpg" class="chalmersPosition-FloatLeft" alt="" style="margin:5px" /><span style="background-color:initial">The Baltic Sea is the largest brackish sea in the world and is classified by the International Maritime Organization, IMO as a Particularly Sensitive Sea Area. Being an almost enclosed basin, the Baltic sea suffers from eutrophication due to inflow of nutrients, phosphorus and nitrogen and a low water exchange frequency. Under eutrophication conditions, marine ecosystems are characterized by intense algal growth, increased oxygen consumption, oxygen depletion with recurrent internal loading of nutrients and death of benthic organisms.</span><div>Phosphorus and nitrogen in the waste discharged from ships are low compared to the total load of nutrients that enter the Baltic sea. However, the shipping in the Baltic Sea is intense and expected to increase, one of the key goals by the European Commission is a shift of medium distance passenger and freight journeys from road to rail and waterborne transport. And with increasing growth of maritime transport and cruise shipping, effective food waste management becomes a pressing issue, Magda Wilewska-Bien writes in her thesis.</div> <div><br /></div> <div><strong>Food waste excepted from regulations</strong></div> <div>In the Baltic Sea discharges of sewage from passenger ships will soon be prohibited, but food waste and grey water (wastewater from dishwashing, shower, laundry etc.) are not included in the coming regulations. Food waste can either be stored for disposal in the port or handled at sea. It is allowed to, with some exceptions and limitations, to discharge ground food waste at sea when the ship is moving at the distance of minimum 12 nautical miles from nearest land and the food waste pieces should not be larger than 25mm.</div> <div><br /></div> <div>It’s a challenge, Marie Wilewska-Bien writes, to get a clear picture on how much food waste that is disposed in the Baltic Sea ports since much information is not publicly available. But an estimation is that the food waste from cargo ships is 0,2-0,5 kg per person and day. For cruise ships 2kg per person and day. An earlier study made in Norwegian waters showed that about 2% of the total generated food waste was discharged to the sea from passenger ships, 40% from bulk carrier, 52% from dry bulk carrier and 92% from general cargo vessel.</div> <div><br /></div> <div><strong>Recover phosphorus</strong></div> <div>The annual contributions of nutrients from ship generated food waste is about 182 tonnes nitrogen and 34 tonnes phosphorus. In the light of an expected global phosphorus scarcity, there is a potential to recover phosphorus and therefore it is preferable to encourage ships to dispose the waste ashore where it can be recycled further to recycle the phosphorus.</div> <div><br /></div> <div>In Magda Wilewska-Biens thesis, a sustainable solution for ship-generated food waste is based on three pillars: the food waste should be separated from other waste streams (1) it should be measured (2) and constantly reduced (3). It should preferably be disposed onshore, where it further is managed to recover energy and valuable constituents.</div> <div><br /></div> <a href=""><div>Read Magda's thesis here &gt;&gt;</div> <br /></a><div><em>Text by <a href="" target="_blank">Lighthouse</a></em></div> Mon, 02 Oct 2017 00:00:00 +0200 initiative seminar - programme ready<p><b>​On 15 November it is time for this year&#39;s Transport Initiative Seminar.
