高超声速进气道流场的磁流体控制
Magnetohydrodynamic control of hypersonic inlet flow
摘要
Abstract
To numerically study the application of the local magnetohydrodynamic( MHD) control on hypersonic inlet flow,two dimensional Euler equations with MHD source terms are solved by using an explicit second order hybrid ROE/HLL scheme. The adaptive mesh refinement technique and immersed boundary method are adopted to handle the complex boundary. The MHD control processes of the scramjet inlet flow with double wedge are numerically simulated. The results show that the two oblique shock waves at the inlet can be controlled by the Lorentz force applied at the forebody of the first ramp,the positions of two oblique shock waves at the inlet can be controlled,and the directions of the Lorentz force have significant effects on the MHD control processes. The two oblique shock waves at off-design conditions can be restored to the desired location by a Lorentz force with proper magnitude and direction,but their flow field structures are slightly different.关键词
