Abstract

Efforts have been made to analyze the performance characteristics of a rough, porous short bearing with slip velocity and thermal effect. The stochastic model of Christensen and Tonder has been used to study the effect of transverse surface roughness in the performance of the bearing system. The effect of slip velocity has been studied by Beavers and Joseph’s slip model. The model of Tipei has been adopted for the thermal effect. The associated stochastically averaged Reynolds type equation is solved with appropriate boundary condition to obtain the pressure distribution, in turn, which gives the expression for Load Carrying Capacity (L.C.C.). The results shown in graphical form establish that transverse roughness and slip velocity induce an adverse effect on the bearing system. In the case of negatively-skewed roughness the situation yields better results. The thermal effect induced negative effect can be retrieved in the case of negative skewed roughness, to certain extent.
