| 摘 要： | 结合表征体元尺度的通用渗流模型，提出离散统一动理学格式（DUGKS）渗流方法，分别用均匀网格和非均匀网格计算二维Poiseuille、Couette、方腔流等经典渗流问题，检验DUGKS渗流方法的有效性和非均匀网格应用的优势，将DUGKS渗流方法应用到裂缝系统中.

| Abstract: | DUGKS is extended to model porous media flow at representative elementary volume scale combined with generalized porous media model. It is verified by several two-dimensional classical problems:Poiseuille flow, Couette flow and cavity flow. Effectiveness of DUGKS for porous media flow is tested and advantage of DUGKS in grid flexibility is demonstrated. A fracture system is modeled by DUGKS for porous media flow. |
