摘要

摘要: 为了探索多孔介质渗透性与孔隙率之间的关系，应用格子Boltzmann方法（LBM）以及无滑移流固边界条件，从孔隙尺度模拟了二维随机多孔介质中的流体流动.通过研究流量和压力梯度的关系，验证了格子Boltzmann方法模拟的Darcy定律.研究结果表明：在孔隙率较低（约小于0.3）的情况下，渗透性与孔隙率近似成指数关系变化，与前人的结果吻合.

Abstract: In order to capture the relation between permeability and porosity, fluid flowing through two-dimensional random porous media was simulated at pore level by enforcing the no-slip condition on the fluid-solid interface. Fluid flow in two dimensional randomly generated porous media was simulated at the pore-scale using the lattice Boltzmann method (LBM). Random media were constructed by placing solid points with a random distribution. The Darcy's law was verified. The research result shows that the permeability varies exponentially with the porosity at low porosity less than about 0.3, being close agreement with the present result.
