Full project title:Computational Fluid Dynamics (CFD) prediction of hydrodynamic forces and moments on a manoeuvring ship in unrestricted and restricted waters

The evaluation of ship manoeuvrability is of significance at the initial design stage. Especially in restricted waters, the hydrodynamic characteristics need to be appropriately predicted since the influence of the flow on the hull may result in significant changes in ship motion, and may lead to problems in ship manoeuvring and navigation. Many tools are available for studying this topic and this project selects a numerical one: Computational Fluid Dynamics (CFD) technique.


Project objectives
The goal is to utilize CFD tools to predict hydrodynamic forces and moments on a ship in unrestricted and restricted water (including shallow-water effects, bank effects and ship-to-ship interaction). The accuracy in predictions is evaluated through formal Verification and Validation (V&V) procedures. With the obtained hydrodynamic quantities, understanding and knowledge of the flow phenomena of importance can be developed and a better prediction of the ship manoeuvring can be made. In the long run, the outcome of this project may lead to safer navigation.
