摘要/Abstract

摘要： 为了研究耐烧蚀材料内部的输运现象,论文使用多点统计方法中的Snesim重构了三种2D多孔介质,并使用格子Boltzmann方法(LBM)模拟了不可压条件下2D多孔介质内的流动与传热现象。模拟结果表明:Snesim方法能够获得耐烧蚀材料的孔隙结构,且资源消耗少；多孔介质内的流动与传热现象与多孔介质结构相关,简单多孔介质中,速度和温度的分布相对比较均匀,复杂多孔介质中,不均匀的流动对温度分布有显著影响。 

Abstract: In order to study the transport phenomena in ablative material, three porous structures were reconstructed with Snesim method of multiple-point statistics in this article, and the flow and heat transfer phenomena in 2D porous media, with the condition of incompressible, were simulated with lattice Boltzmann method (LBM). The simulations show that the structure space of ablative material can be obtained with Snesim, while the consumption of resources is less.The flow and heat transfer phenomena in porous media are related to the structure of porous media, the distribution of velocity and temperature are relative uniform in simple porous media, while the flow of non-uniform has a significant effect on the temperature distribution. 
