摘要 研究相变材料围绕J =1/2 ,2水平椭圆柱在有限长接触时的温差熔化过程 .应用边界层理论求得熔化边界层厚度 ,作用力与熔化速度关系式 .讨论了有关结果 ,并与长椭圆柱以及有限长圆柱的温差熔化的结果进行了比较 。 The finite length contact melting around a moving horizontal elliptical cylinder, which has compression coefficient J=1/2, 2 respectively, is investigated. The film thickness of liquid and the relation between the force exerted on the elliptical cylinder and the melting velocity are obtained analytically. The results are discussed and compared with that of infinite length contact melting around an elliptical cylinder and finite length contact melting around a cylinder, respectively. Some useful conclusions are drawn.
