Abstract
The main purpose behind this paper is to analyze the groove’s dimensions effect on the pressure profile of hybrid journal bearing. To find the pressure developed in the bearing’s clearance space for any Sommerfeld number, an objective function that corresponds to the solution algorithm along with its computer program is developed. The solution algorithm shall also provide three-dimensional pressure profiles of the bearing for different lengths and widths. It is discovered that the dimensions of the grooves mainly influence the performance parameters as grooves have a strong interference in the hydrodynamic condition of the pressure field. It was observed that the groove length ratio and width ratio should be taken as 0.8 and 0.1, respectively, for better load bearing capacity of the bearing.
