The influences of MHD control direction on the hypersonic inlet flow

Abstract

Local MHD hypersonic flow control of a scramjet inlet has been conducted in this paper. Two dimensional Euler equations with MHD terms are used for describing the flow filed variations during the control process. An explicit second order Godunov-type scheme is employed to solve the equation, the immersed boundary condition and a block-structured adaptive mesh refinement technique are adopted to handle the complex boundary and high pressure gradient, respectively. Our numerical results show that the MHD control can be used to restore the oblique shock waves at off-design conditions with the force applied at the forebody of the first ramp in proper directions.
