    Abstract
  • The magnetohydrodynamic (MHD) controlling of hypersonic boundary layer and hypersonic inlets in off-design conditions were studied by magnetohydrodynamic control system based on electron beam ionization.The governing equations were low magnetic Reynolds number Navier-Stokes(N-S) equations,and the plasma kinetics model coupled with electron beam model was developed to simulate air ionization.Results indicate :(1)The electron beam ionization can improve the conductivity of flow and the control efficiency of magnetic field .(2)The MHD system can effectively control the hypersonic boundary layer and the control efficiency closely related with the electron beam energy .(3)The MHD system can bring oblique shock in off-design conditions back to the location of shock-on-lip(SOL) condition,and the total pressure recovery coefficient and flow mass of inlets would be reduced.
