Scholarcy highlights

  • We report a comprehensive, experimental study to examine the lubrication theory for highly compressible porous media
  • It is inspired by the frictionless motion of red cells in a tightly fitting capillary and a human skiing/snowboarding
  • A novel experimental setup was developed where lubrication pressure generated in a soft porous layer was measured as planar board glides over it
  • The paper demonstrates the significant potential of applying soft porous media in lubrication with tremendously enhanced hydrodynamic lift
