非均匀多孔介质渗透率粗化的有限分析算法
Upscaling Algorithm for Heterogeneous Porous Media by Using the Finite Analytic Method
摘要
Abstract
An algorithm for solving upscaled tensor permeability by using the finite analytic method is proposed,which is suitable for the flow field described by the linear Darcy′s law. Adoptingthe double periodic boundary condition proposed by Durlofsky,the proposed algorithm can provide the upscaled full tensor permeability with high efficiency. Only with 2×2 or 3×3 subdivisions,the proposed algorithm can provide rather accurate solutions,where the convergent speed is independent of the permeability heterogeneity. In contrast,when using the traditional numerical schemes to simulate flow through a strong heterogeneous porous medium,the refinement ratio for the grid cell needs to increase dramatically to get an accurate result.关键词
