Our research laboratory specializes in the numerical simulation of plasma & reactive flows such as those used in flow control, in plasma-assisted combustion, in plasma-based fuel reforming, as well as in plasma medicine. The plasma technologies here considered can improve the performance of aircraft either through Dielectric Barrier Discharge (DBD) actuators to increase the critical angle of attack of airfoils and to anchor flames in fuel-lean mixtures, or through gliding arcs to transform a hydrocarbon fuel into hydrogen to be consumed by fuel cells, or through Magneto Hydro Dynamics (MHD) devices to generate power or to prevent shock-induced boundary-layer separation. In our laboratory, we aim to improve the efficiency of the numerical methods and models needed to simulate plasma & reactive flows as well as to use such methods and models along with our CFD code WARP to design more efficient DBD and MHD devices.
