• A transient laminar jet was simulated by numerical computations based on the time-dependent conservation equations of mass, momentum and species with variable density and viscosity in a two-component gas mixture. The flow and mixing process in cooperation with vortex formation predicted by computations were compared with the experiments. The results indicate that (1) the flow field is characterized by the superposition of convection in the axial direction and the rotation by vortices formed in the jet, (2) the vortices entrain the surrounding gas which is laminated in the vortices to enhance mixing, and (3) the computed results simulate well the characteristics of the flow and mixing processes observed in the experiments.
