Abstract

Fluid pressurization in a compressible porous media is critical for the normal functions of biological systems, e.g., knee joint lubrication or the smooth motion of red blood cells. Despite extensive research, a theory that precisely captures the pressurization process is still lacking. Herein, we report a novel two-domain model featuring a deforming porous domain under the loading surface and a peripheral undeformed porous domain. The theoretical predictions excellently agree with the experimental study by Crawford et al. (J. Porous Media, vol. 14, pp. 51–64, 2011). The study lays the foundation for characterizing a fluid flow in compressible porous media. It has broad soft porous lubrication applications in both biological systems and industry.
