摘要

This article presents the transient conjugate heat transfer characterization of a free liquid jet impinging on a rotating solid disk of finite thickness and radius. Calculations were done for a range of Reynolds number (500-1400), Ekman number (6.62 x 10~-5-oc), disk thicknesses to nozzle diameter ratio (0.17-1.67), and solid to fluid thermal conductivity ratio (36.91-697.56) using water as the coolant. It was detected that the duration of the transient increased with disk thickness and decreased with Reynolds number and thermal conductivity ratio. A correlation for average Nusselt number for the transient heat transfer is presented
