| Abstract: | 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. |
