摘要
利用有限元耦合场数值模拟计算方法进行了高温钢板纯水喷雾冷却的模拟，研究了射流出口高度和钢板表面温度对换热系数的影响．模拟结果表明：在其他参数不变的情况下，随喷射距离（在200～500mm范围内）的减小，换热系数总体呈增加趋势；随钢板表面温度（在1050-200K范围内）的增加，换热系数总体呈减小趋势．
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 .
