Abstract

Abstract

Spray cooling of a high-temperature steel plate was simulated by using finite element method. The effects of surface-to-nozzle distance and steel plate's surface temperature on spray cooling heat transfer coefficient were analyzed. The simulation results show that on condition that other parameters retain constant, the heat transfer coefficient increases totally with decreasing jet space (200~500mm) and decreases totally with the surface temperature increasing when the surface temperature of the plate in 1050~1 200K.
