Numerical Behavior of Mixed Convection in a 2D Channel with a Co-Flowing Fluid Injection from a Flat Nozzle

摘要

In this paper, a numerical investigation which concerns a mixed convection flow in a two-dimensional vertical heated channel is performed. This flow results from the mixing of the up-going fluid along the channel walls with the one issued from a flat nozzle located at its entry section. The system of governing equations is solved with the finite volume method together with an implicit scheme. The obtained results prove the activation of heat transfer by the combined effect of turbulence and jet-wall interactions. This activation is also realized by the drive of ambient air by the jet.
