摘要: 多孔介质在诸多领域有着广泛应用，了解其特性具有重要意义。为对多孔介质中相关流动与传热特性进行研究。本文通过四参数随机生成法获得多孔介质数字模型，在此基础上利用改进的格子Boltzmann方法对多孔介质内部的流动与传热问题进行了数值模拟。得到了不同孔隙条件下，多孔介质内部温度场、速度场以及有效导热系数。结果显示，在内部流体工质流动状态下，多孔介质导热系数会受到流体流动影响，有所提高。本文为多孔介质相关流动与传热特性提供了一种可靠的模拟方法。
Abstract: In this paper, a digital model of porous media is obtained by four-parameter stochastic generation method. And an improved lattice Boltzmann method is used to simulate the flow and heat transfer problems in this porous media. The distribution of velocity and temperature is obtained at different porosity. On the basis of the results, the effective thermal conductivity of porous media is calculated. And the value is affected by the flow state in porous media. A reliable simulation method for study flow and heat transfer in porous media can be obtained in this paper.
