自由表面二维平面射流冲击传热的理论分析

摘要

对二维平面射流冲击平板时的层流流动（和传热）给出了速度和温度边界层的综合解析,用积分方法得到了平面射流冲击传热的驻点区和部分壁面射流区的换热关系式,并将等热流壁面的分析结果与实验数据进行比较，结果基本吻合．%An analytical research was conducted to iwvestigate heat transfer from target surface to impinging free-surface slot jests． The laminar hyolraulic and themal boundary layers were analyzed using integral method. Heat transfer coefficients were providecd both in stagnation zone and wall jet zone. Good agreement was obtained between the present analytical vesults and the experimental data from reference.
