Numerical Study of Two-Dimensional Co-Flowing Turbulent Jets

The present study reports numerical analysis of turbulent jets. This study investigates the effect of initial jet velocity on the location of the merging and combining points of two dimensional co-flowing turbulent jets. Flow geometry under consideration is three co-flowing rectangular jets. Effects of inner jet and outer jets exit velocities are investigated. Numerical results are obtained with a finite volume CFD code. Turbulence is treated with a two equation k-e model. Different jet velocities have been examined corresponding to Reynolds numbers of 2,000 to 35,000. Structured grids are used in the present study. Results show that the initial velocity of the inner jet has significant effect on the merging and combining points.
