摘要
A large-eddy simulation (LES) model using a local dynamic kinetic energy model (LDKM) for closure is used to investigate the effect of applied magnetic and electric fields on the flow development in a supersonic step-combustor. The magnetohydrodynamic (MHD) equations are solved numerically using a finite volume method with a multi-state approximate MHD Riemann solver to compute the fluxes. The resistive fluxes in the magnetic induction equation are determined using an analytical approximation in order to relax the time-step constraint. The results show the capability of external fields to control and/or change supersonic shear flow and their potential for mixing and combustion enhancement.
