Abstract
The present paper numerically investigates the effect of a co-flowing stream on the mean and turbulent flow properties, air entrainment and entropy generation rate of a heated turbulent plane jet emerging in a co-flowing stream. The first order k-e turbulence model is used and compared to the existing experimental data. The Finite Volume Method (FVM) is used to discretize the governing equations. The predicted results were consistent with the experimental data. It is found that a jet in a co-flowing stream is known to be a quicker mixer than a jet in a quiescent ambient, and it is proved that the presence of a co-flow enhances mixing. Therefore, the mixing of a jet in co-flow is more efficient.
