Visualizing complex pore structure and fluid flow in porous media using 3D printing technology and LBM simulation
3D printing Pore structure LBM Visualization
2018/3/23
Pore structures of porous media and properties of fluid flow are key factors for the study of non-Darcy groundwater flow. However, it is difficult to directly observe pore structures and flow properti...
含裂隙煤体瓦斯渗流规律的LBM数值模拟
格子Boltzmann方法（LBM） 裂隙煤体 瓦斯渗流
2013/12/6
通过模拟外力驱动渗流以及部分填充多孔介质的剪切渗流，验证了广义LBM模型可以对含有裂隙的煤体内瓦斯渗流规律进行模拟研究；裂隙内的流速明显高于在煤基质内的流速，定量研究了渗流速度和流量随着裂隙宽度增加的变化规律；而在裂隙宽度相等的条件下，煤体渗透率越低则流速和流量的提高越显著；与顺流向的裂隙相比，垂直流向裂隙的存在对提高渗流速度及流量的影响相对较为有限。模拟结果表明：裂隙的存在，尤其是在渗透性较差的...
