Numerical study of the dynamic behavior of a hydrostatic bearing with four pads lubricated by a micropolar fluid

Abstract

This work presents a numerical study on the effects of characteristic parameters of micropolar fluids and the pressure ratio on a four-pad hydrostatic bearing used as a hydrostatic squeeze film through capillary-type hydraulic resistances. To determine the pressure distribution, the modified Reynolds equation is solved using the finite difference method and the Gauss-Seidel iteration. The results show that bearings lubricated by micropolar fluids exhibit an increase in pressure in the recesses, suggesting that performance is mainly influenced by the pressure ratio.
