Abstract

This paper discusses the effect of the horizontal movement of impinging jets on the convective heat transfer from a cylindrical concave surface. In this way, the averaged Navier-Stokes equations for turbulent incompressible flow in a steady state considering two prevalent turbulence models and a Low- Re model with the YAP CORRECTION in the 3D computational space were solved. Results indicate that the YAP CORRECTION significantly improves the over-prediction of NUSSELT NUMBER in the impingement zone. The results show that the decrease in the distance of the center of the jets to the outlet edge of the concave surface leads to the transfer of the maximum amount of the NUSSELT NUMBER to the upstream flow, and the approach of the main flow of the jet to the recirculation region formed in the upstream flow results in the increase in the turbulent kinetic energy of this area and the NUSSELT NUMBER in the stagnation point.
