Numerical Simulation of Jet and Cross-Flow Mixing in Tee Pipe

Abstract

In the present paper we investigated the mixing effect of uncompressible jet and cross-flow in Tee pipe based CFD, the model of Realizable was employed as the tool to simulate the flow field, and the model was validated by experimental result of relative research. The mixing effect of jet and cross-flow in various configuration of Tee pipe at different inlet velocity of jet was discussed. The result shows jet and cross-flow mix quickly in near field of injection point, but in the downstream, the mixing effect keeps comparatively steady whenz>7d, and there is power relation between the mixing parameterMandr1×r2. Andr1is the ratio of jet pipe diameter to cross-flow pipe diameter,r2is the ratio of jet velocity to cross-flow velocity.
