This paper shows the various arrangement for location of groove for two groove hydrodynamic journal bearing for optimum performance. In the present work the effect of different location of oil groove on the performance of hydrodynamic journal bearing has been observed. The basic Reynolds equation is nondimensionalized by using proper substitutions and then it is solved numerically by using finite difference method satisfying the Reynolds boundary condition. Determination of optimum location of groove is based on the maximization of nondimensionalized load carrying capacity and flow coefficient and minimization of friction variable. Initially both the groove has been placed at diametrically opposite directions but in this work the optimum location arrived, are not the diametrically opposite.
