Investigating the effects of chevron-textures on the performance of a porous journal bearing

Abstract

Abstract The present article aimed for investigating the fluid-film pressures for chevron-textured porous journal bearing. The Reynolds equation for porous bearing has been adopted as governing equation, we took the Reynolds boundary conditions into account. The numerical computation has been performed with the help of finite difference methods. The numerical model is well validated with the previous work of researchers. The calculated results revealed that the incorporation of chevron-textures in the convergent zone significantly increase the film pressures as compared to smooth bearing case which ultimately lead to improve the tribological performance. Moreover, permeability play a detrimental role in enhancement of film pressure but incorporation of texture definitely compensate to these effects up to some extent.
