Abstract
The present study is an initiation to investigate the effect of plate movement on heat transfer characteristics in the solid plate and the fluid domain due to the turbulent wall jet flow over the plate in a quiescent surrounding. A conjugate technique is used to carry out the heat transfer solution that involves conduction in solid and convection in fluid coupled at the interface surface. The plate is heated continuously with a constant flux at its lower surface. A low-Reynolds number turbulence model developed by Yang and Shih (YS) is applied to simulate the turbulent flow. The parameters considered for the present study are the plate-jet velocity ratio
the plate thickness ratio
the conduction ratio
and the Reynolds number
The temperature distribution diagrams for various plate velocities, the interface temperature profile, and the averaged Nusselt number show a higher cooling rate at high plate-jet velocity ratios. The effect of plate thickness and conductivity ratios is visible in the temperature distribution diagrams. A better heat transfer is achieved at a higher Reynolds number, evident from the averaged and local Nusselt number distribution. A correlation is developed for average Nusselt number with the Reynolds number and plate-jet velocity ratios as the varying parameters.
