摘　　要：用尾流特征参数确定水下航行加热体热阻力的计算方法陈伯义，杜先之（海军工程学院蒸汽燃气核动力工程系武汉４３００３３）关键词热阻力；水下航行加热体，尾流１引言在工程上，对于传热与流动同时存在的问题，过土常常主要研究流动时传热的影响，而很少考虑传热过程对流...This paper obtains the relationship between the thermal drag and the characteristic parameters of wake flow behind a heated body of revolution going underwater by means of a semi-empirical analysis method, thinks that the thermal drag is practically a driving force for the heated body, and gives the semi-empirical computational formulas of the thermal drag coefficient and the total drag coefficient of the body. Furthermore, the velocity profiles and the temperature distributions of the wake flow are measured by a laser velocimeter and by a thermistor respectively.
