摘　　要：通过转轴和移轴的方法,研究了在稳态温度场中二维任意形填充流道边界的动态热应力分布问题,并给出了此问题的一般解析解,也得到了二维任意形填充流道边界的动态热应力分布系数的计算方法.作为一个具体的算例,给出了二维填充椭圆孔边界的动态热应力分布问题的数值结果,并进行了讨论.The thermal dynamic stress distribution of the surface of a channel filled with fluid media was studied through the translation and rotation of coordinates. A general analytical solution with the computional details was presented. As an illustration,the thermal dynamic stress distribution of the surface of an elliptic channel filled with flow media were shown in the figures with numerical results.
