Lubrication of Squeeze Film Between Porous Rough Circular Plates with Rabinowitsch Fluid Model

Abstract

In this paper it is analyzed that the theoretical study of lubrication of squeezing film connecting rough circular porous plates with Rabinowitsch fluid. By using Christensen’s stochastic theory for the lubrication of hydrodynamic rough surface modified Reynolds equation is derived. The patterns of  roughness of surface are considered in 1-dimensional for two types, which are radial and azimuthal roughness patterns. Squeeze film time, load support and pressure expressions are gained. In both radial and azimuthal patterns the squeezing film time, load carrying capacity and pressure are decreases in porous roughness pattern on the surface.
