Abstract

Numerical simulation of two phase spray impingement on a heated wall was carried out. Hybrid turbulence modeling was used for analysis where large eddy simulation was employed away from the wall, and a k-epsilon model was employed near the wall. The effect of vortex motion on turbulent heat flux values was analyzed using different Reynolds numbers of impingement and at different angles. It was observed that the turbulent heat flux attained maximum values with high vortex formation. The ejection of hot fluid from the surface was predominant when compared to the down sweep motion of the cold fluid. The Nusselt number plot indicated high heat transfer rates for higher Reynolds number.
