Doctoral student Daniel Lindblad has worked with calculating noise from
aircraft engines using computer simulations. They are usually cheaper to
perform than physical tests, which means that those who manufacture components
can afford to test several different variants of each component before moving
on and testing the best alternatives in real life. However, for the selection
process to be as good as possible, the simulations must be reliable.
“In my PhD project, I have worked with evaluating and improving existing
models, which also contributes to an increased understanding of the methods
used today” says Daniel Lindblad.
Several areas where improvements can be made
Daniel's research has shown that today's methods are already very well
developed, which underlines the competence that exists in the aviation industry
and aviation research today. However, there are several areas where
improvements can be made, and Daniel Lindblad is happy that he has been able to
contribute to this.
“I have mainly contributed to an increased understanding of the
advantages and disadvantages of different methods for simulating noise from
aircraft. I have also suggested improvements to several methods, which
hopefully means that future simulations will be better” says Daniel Lindblad.
By collaborating with the University of Cincinnati and the German
Aerospace Center (DLR), both of which have strong ties to the industry, he
hopes that the results will also be adopted in practice.
Daniel Lindblad will defend his dissertation Numerical Methods forAeroacoustic Analysis of Turbomachines on September 25 at 14.00.
