This project is performed to find the effectiveness of jet impingement cooling system. The parameter that had being selected is mass flow rate (4.5m/s, 8.4m/s, and 12.8 m/s) and nozzle to surface distance, s (3cm, 6cm and 9cm). The mas flow rate that been chosen to consist of one transition flow and three turbulent flow. The experiment results can show the relationship between heat transfer coefficient with mass flow rate and nozzle to surface distance. In overall, cooling effect is better when the Reynold number is bigger and medium distance of nozzle to surface distance. The higher the Nusselt number and heat transfer rate shows the higher heat loss to the surrounding, mean that more effective of the cooling mechanisms. Nozzle to surface spacing has some significant effect on the surface curvature c/d. The higher Reynold number enhances the heat transfer and this will cause higher the Nusselt number. The Nusselt number is highest at stagnation point of c/d = 0. From this experiment, the best cooling effect is at (Reynold number=4903.45, c/d=0, s=6cm) with the Nusselt number of 70.8679 fahmimoksen UTM 82 p.
