| 摘 要： | 提出了耦合求解焓及移动边界位置的多维相变传热问题的数值焓法。方法的基本特征是通过变换标准的焓公式,分离显热与潜热项,并在引入轴间相变率概念的基础上,将其耦合到潜热源项中,同时对流入/流出相变控制容积的热流密度加以修正,以达到既能提高数值解的精度,又可以达到准确跟踪移动边界的目的。

| Abstract: | A numerical enthalpy method is proposed for solving the multi-dimensional
phase change problem by coupling the enthalpy and the moving boundary. Its basic feature is to sepasate appearent and latent heat terms by transforming the standard enthalpy relation and to couple them into the latent heat term by introducing the idea of phase change rate between the axes and simultaneously to correct the heat flux of the inflowing/outflowing phase change control volume element , so that the accuracy of numerical solution is improved and the moving boundary can be accurately followed. |
