Numerical simulation of a two-dimensional scramjet MHD controlled inlet

Two-dimensional in viscid steady-state flow equations coupled with MHD effects are solved jointly with MHD equations to study the performance of an MHD controlled inlet when flight Mach number is larger than the design value. At a proper choice of parameters the shocks are moved back to the cowl lip, and the outlet parameters became evener. The influence of the MHD interaction location, width and depth to the MHD controlled inlet has been analyzed, the calculations show that in order to make the outlet flow evener the MHD region should be placed upstream and penetrate into the flow deeper. With a wider MHD interaction region, smaller magnitude of the magnetic induction is needed to move the shocks back to the cowl lip.
