微重力条件下固液相变过程空穴移动特性研究

为了解微重力条件下固液相变传热过程中空穴的移动特性，建立了一种基于温度排序算法的空穴模型，研究了空穴在不同初始位置的移动过程。结果表明，不同初始位置的空穴均沿着热流的反方向移动，在相同热边界条件下空穴的最终位置与初始位置无关。

Void migration characteristics during solid-liquid phase change process under microgravity condition

In order to study the void migration characteristics during the solid-liquid phase change heat transfer process under the microgravity condition, the void model based on a temperature sorting algorithm is built and the void migration process at different initial positions is studied. It is shown that the void at different initial positions moves to the opposite direction of the heat flow. The final position of the void is not related with the initial position when the thermal boundary condition is the same.
