Multi-dimensional hydrodynamics computer codes are used to investigate jet penetration and fluid mixing patterns of main and jet flows in an MHD second stage combustor. The computer simulation is intended to enhance the understanding of flow and mixing patterns in the combustor, which in turn may improve downstream MHD channel performance. A two-dimensional code is used to study the effects of jet angle, jet velocity, and turbulence parameters on the fluid mixing and a three-dimensional code is used to examine the effects of the jet port configuration and inlet swirl on the fluid mixing. Both codes solve the conservation equations of mass, momentum, and energy, in conjunction with a turbulence model. The mixedness (degree of mixing) of jet and main fluids depends greatly on jet angle and jet velocity. Counter-flow injection of jet fluid and high jet velocity are required to have a satisfactory fluid mixing for MHD combustor applications.
