| 摘 要： | 本文介绍了求解一维常物性动边界问题的MVTS方法,对其迭代方法作了较为彻底的改进,大大减少了计算时间。文中还将VTS方法推广到一维变物性动边界问题,提出了直接计算法,与目前工程上较为通行的变换法作了比较,结果表明直接法比变换法有更大的优越性,可以大大减少计算工作量。

| Abstract: | The MVTS method for solving one-dimensional constantproperty moving boundary problem is briefly described and improved. The new methods are proposed for estimating the initial iteration value of time step. By the qse of these new methods, the computing time can be greatly shorted. The variable time step method is extented to solve one dimensional temperature-dependent-property moving boundary problem in this paper. Comparing with the transformation method widely used in current, the direct method is more effective. The numerical solutions for both constant-property and temperature-dependent-property moving boundary problems are obtained. |
