Fluid Flow and Heat Transfer in an Opposed Plane Jet in an Uniform Stream (Analysis in Unsteady Motions)

Abstract

The purpose of this report is to investigate the fluid flow and heat transfer in an opposed plane jet in a uniform stream. In the previous paper, experimental results indicated that there were unsteady motions of low frequency and large scale, which are known as jet flapping. In the present paper, the unsteady motions for the Reynolds number of a jet, Re0=1500, and the ratio of the jet to uniform stream velocity, α=3.75, are studied numerically by the finite difference method. Previous experimental results are simulated in outline by numerical calculations. Time histories and instantaneous or time-averaged contours for velocity, pressure coefficient and temperature are obtained, and the mechanisms of fluid flow and heat transfer are clarified.
