POROUS CURVILINEAR SQUEEZE FILM BEARING WITH ROUGH SURFACES LUBRICATED BY A POWER-LAW FLUID
RESUMO
The flow of a power-law lubricant in a squeeze film bearing with one porous wall is considered. The bearing is modeled by two curvilinear rough surfaces and the porous wall adheres to the curved nonporous surface. The flow in the bearing clearance is considered without inertia and the momentum and Poisson equations are uncoupled by using the Morgan-Cameron approximation. A closed-form solution is obtained by using the Christensen stochastic model of surface roughness. A step bearing and a spherical bearing are discussed as examples. It is shown that the power-law exponent and the roughness influence the bearing performance considerably.
