摘要:

相变是传质传热中的一种典型情况。而多孔介质中物质的相变在工业生产和日常生活中十分常见。由于相变问题的非线性特点,需要格子Boltzmann方法这种能够模拟流体运动以及为复杂物理现象建模的数值方法来处理它。本文运用格子Boltzmann方法对纯相变以及多孔介质内物质的对流相变过程进行了数值模拟,并对数值结果加以研究和讨论。发现不同的达西数对多孔介质内的对流相变过程中有重要的影响。

Phase change is a basic problem in heat and mass transfer field, especially in porous media. In this work, as it’s nonlinear characteristics, Lattice Boltzmann method (LBM) is used to numericaly simulate the heat and mass trans- fer coupling with phase change in porous media, and results showed that different Darcy Numbers have some certain effects on phase change process in porous medium.
