The parametric experiments were performed for Reynolds numbers ranging from 10,000 to 40,000, nondimensional nozzle-to-plate spacing of 32–56, and loading fraction ranging from 0 to 1%. The present study indicated that the Reynolds number (Redhyd ) and the loading fraction (f) increases the Nusselt number, whereas increasing the h/d ratio adversely affects the cooling. It is concluded that the loading fraction has the highest impact on the cooling controllability, while the Reynolds number and the h/d ratio have a secondary and tertiary impact on the cooling. Furthermore, based on the experimental results, a correlation function is developed. It is elucidated that a good correlation function can act as a better alternative over costly and prolonged experiments. %8 2019-09-09
