Abstract
The aim of the present study is to numerically simulate the cooling of heated moving surfaces under water jet impingement and study the associated flow and heat transfer characteristics. The investigation includes the effects of surface curvature ratio (d/D), nozzle-to-surface spacing ratio (H/d), Reynolds number (Re) and surface motion (
or 
). The flow field and thermal field under varying process conditions in the stagnation and wall-jet regions are studied. The results include velocity distribution, temperature distribution, localized heat transfer, average and stagnation Nusselt numbers at an intermediate time-step. The study reveals that surface motion significantly impacts heat transfer and flow characteristics for both curved and flat surfaces. Stagnation Nusselt number and average Nusselt number are approximately 46% and 23% greater for higher velocity cases. The area-averaged heat transfer over a moving plate is 6% more than a rotating cylinder.
