A parametric study of a porous self-circulating hydrodynamic bearing

► The concept of self‐circulation is viable and depends on the reservoir depth. ► Joint use of the 3D Navier-Stokes equation and Brinkman equation. ► The clearance‐porous matrix‐reservoir assembly is treated as a continuum. ► Permeability controls pressure in the bearing clearance and reservoir. ► Permeability and porosity are both affecting fluid circulation and pressure.
