ABSTRACT
This study presents the Experimental and Computational Fluid Dynamics (CFD) analysis on Jet impingement cooling. Jet impingement is highly effective convective heat transfer technology and improving heat transfer enhancement in various applications. The fluid flow and heat transfer characteristics of jet impinging on circular copper plate is investigated by experimentally and CFD analysis were done. This study on jet impingement cooling is conducted to optimize the parameters like 6 mm and 8 mm nozzle diameters, Distance between jet to target spacing have taken 10 cm (h/d) and the velocity of the jet (3 LPM,5 LPM,8 LPM). Experiment has conducted with water as coolants .Experimental data is recorded as per requirement and results are validated by using CFD simulation, it gives the rapid cooling rate. This study shows the result about Reynolds number increases with decreasing temperature and Nusselt number increases as the flow rate for different nozzle diameters increases. Form this analysis, obtained optimum cooling range with 6 mm and 8 mm diameters when h/d consider 10 cm with various flow rates. The results shows maximum Reynold no. is at 6 mm nozzle diameter and maximum Nusselt no. is as 8 mm nozzle diameter. There is good results agreement in between experimentation and CFD simulation.
