A three-dimensional hydrodynamics computer code was used to investigate the flow mixing processes in an MHD second stage combustor. The code solves the conservation equations of mass, momentum, energy, and a transport equation of turbulence kinetic energy. The flow mixing patterns of four different jet port arrangements, including a 12-jet, an 8-center-jet, an 8-side-jet, and an 8-mixed-jet (4 side and 4 center jets), were computed and compared. Jet and gas seems to mix in two stages: an early and more effective convective stage and a later diffusive stage. For the same bulk jet concentration, the 12-jet arrangement has better jet-gas mixing than the other three 8-jet arrangements. 8 refs., 8 figs.
