Abstract
In the electrodynamic flow control, a weakly-ionized plasma flow behind the strong shock wave is expected to be controlled by the applied magnetic field around a reentry vehicle. According to the recent experiment using an arc-jet wind tunnel, it was observed that the electrodynamic flow control is affected by the magnetic field configuration such as the magnetic field inclination. In this study, the numerical MHD simulation was performed to investigate the electrodynamic flow control affected by the inclination and the intensity of the magnetic field. It was found that the aerodynamic force, not only the axial but also the normal force, is affected by the magnetic field inclination. The modification of the electric current distribution and the flow field is responsible for such a phenomenon. The manner of the variation of the aerodynamic force associated with the magnetic field inclination strongly depends on the magnetic field intensity. That is, once the magnetic field intensity exceeds a threshold value, the manner changes drastically. The drastic change of the flow field represented by the circulation region is responsible to this drastic change observed in the manner of the variation of the aerodynamic force associated with the magnetic field inclination.
