Abstract
A self acting, finite length, partial porous journal bearing with arbitrary load angle has been analysed to obtain the characteristics assuming the active film of a homogeneous single phase liquid lubricant extends over the whole bearing arc span. The adhesion condition used in earlier porous bearing analysis is no longer valid, due to the presence of the thin layer of fluid moving streamwise just beneath the surface of the porous bearing material, a new modified lubrication equation is used for the present analysis. Film curvature has been considered. The curvature effect of the thick porous bearing matrix is taken into account by a direct but new approach which makes possible the use of the separation of variables for the first time in such a problem. Collocation technique is utilised to determine the hydrodynamic pressure from which characteristics are evaluated as usual. The results are fully analytical in nature, simple, yet exact and accurate, permitting easy and economical calculation of numerical data over a very wide range of parameters.
