This paper investigated flow and its oscillatory behavior in the intersecting region of converging/diverging flow pairs. Flow control was performed by placing a turbulence mesh at the flow exit inside one of two upper flow supply tanks. The angles of converging flows and of subsequent diverging streams were varied. Velocity-vector and power spectrum distributions were obtained by LDV. It was then used to calculate the distributions of vorticity, turbulence intensities in the longitudinal and lateral direction, and Reynolds stress. Of importance is the velocity variation along the shear layer in the intersecting region. This exhibits a peak, referred to as the energy supply point, downstream from the center of the shear layer. Hence, the total kinetic energy resulting from the collision of two converging streams which occurs between the converging point and the peak is released over the range between the peak and the diverging point. This is the sole basis for evaluating heat transfer performance of a flow network. This observation is further strengthened by the power spectrum distribution.
