Inertia and slip effect on a single textured hydrodynamic thrust bearing using CFD methods

Abstract

Increasing bearing performance in load support can be done by adding texture and artificial slip on one of the bearing surfaces. In this paper, a study is presented on fluid inertia and slip effect on the performance of textured hydrodynamic thrust bearings in load support by considering both cavitation and without cavitation. The results obtained indicate that cavitation needs to be considered in the bearing analysis. Moreover, the greater the fluid inertia force is, the less load support will be produced in a slip condition, but in a no-slip condition, adding artificial slip can increase the load support in thrust bearings at a certain sliding speed.
