Active flow control for reduced resistance of trains, trucks, and ships

Active flow control techniques have received great attention in recent years from vehicle manufacturers as it has the potential to improve aerodynamic drag further after shape optimisation/styling has been performed. Active flow control can also be better adopted to varying operating conditions. In ship design, aerodynamic design has traditionally often not been considered important, although making up a significant contribution to drag for certain vessels; the focus has been on hydrodynamic resistance. This project will investigate fundamental principles of active flow control, partly to support the already active development within the vehicle industry, but primarily to look at expanding these applications to trains and ships, yielding a potential for improved efficiency for all modes transportation.
