ADVANCES IN RESEARCH ON FLUID-SOLID COUPLING SEEPAGE IN POROUS MEDIA

The important significance for the research on fluid-solid coupling seepage in porous media is introduced.Developments of the fluid-solid flow in the porous media are reviewed;and the further research directions are also presented.Particularly,studies on the fluid-solid coupling multiphase flow and its application and studies on various coupling methods in the last ten years are discussed.The fluid-solid coupling flow is concerned chiefly with flow of oil and gas through porous media.It is considered that the establishment and development of interaction cupling for multiphase fluids and multifield models and its numerical method have great meanings of the fluid-solid coupling mechanics.
