Influence of Surface Texture on the Performance of Hydrodynamic Porous Journal Bearing

Ashish Kumar, Dinesh Kumar

Abstract: In the Present study we reveal the effects of surface texture (spherical dimple) on the performance of porous journal bearing by incorporation these dimples in particular location. The numerical work has been performed with the help of computational technique and it has been concluded that the influence of spherical type of texture (spherical dimple) on the bearing performance is very appreciating. The location of dimples in the particular location has been suggested with reference to the work of previous researchers. The modified governing equation (Reynolds equation) is solved computationally through finite difference method and Simpson?s 1/3rd rule and over relaxation method are used in calculating the various bearing parameters such as load carry capacity eccentricity ratio fluid film pressure etc.

Keywords: porous journal bearing; surface texture; finite difference approach; spherical dimples.
