A numerical solution describing a two- dimensional turbulent flow field with multiple gas species was used to study the interaction and mixing of opposed slot jets with the main flow in a rectangular channel. This paper is part of a program to use computer modeling to aid in the design of a magnetohydrodynamic second-stage combustor. The effects of varying the jet angle and main inlet flow symmetry on the mixing patterns and rate of mixing were evaluated using computed velocity and species concentration fields. Mixing depends strongly on jet angle, and jet angles greater than 90{degrees} produce better mixing.
