摘　　要：利用计算流体力学软件FLUENT,采用不可压缩流体流动基本原理和流热固耦合有限体积方法,研究了单孔圆形喷嘴射流冷却带钢的冲击换热,得到了在不同参数和边界条件下冲击射流冷却带钢的传热特性及喷射距离、喷射介质的压力和温度及喷射介质中氢气含量对传热系数的影响,为提高带钢冷却速度提供理论参考。The impinging heat transfer during eooling strip steel in a fluid from single-jet nozzle was investigated by means of the computational fluid dynamie software FLUENT, basic theory of incompressible liquid flow and liquid - thermal coupling finite volume method. As a result, the heat transfer characteristie and the effect of injecting distanee, pressure and temperature as well as hydrogen eontent of injecting medium on heat transfer eoefficient were clarified when strip steel was eooled by injecting fluid at different parameters and under different boundary eonditions, thus theoretically giving a reference to the increase of cooling speed of strip steel.
