Abstract

The no-slip boundary condition is part of the foundation of the traditional lubrication theory. It has been found by recent experimental research that for certain engineered surfaces no-slip boundary condition is not valid. In the present study the effect of an engineered slip/no-slip surface on journal bearing performance is examined. Numerical Analysis is carried out by solving the modified Reynolds equation satisfying the boundary conditions using successive over relaxation scheme in a finite difference grid which gives the steady state pressure. These pressure values are used to evaluate the dimensionless steady-state load bearing capacity, attitude angle and friction force. It is found that the cautious application of slip to a journal bearing‟s surface can lead to improved bearing performance
