This paper presents the various arrangements of grooving location of two-groove oil journal bearing for optimum performance. An attempt has been made to find out the effect of different configurations of two groove oil journal bearing by changing groove locations. Various groove angles that have been considered are 10°, 20°, and 30°. The Reynolds equation is solved numerically in a finite difference grid satisfying the appropriate boundary conditions. Determination of optimum performance is based on maximization of nondimensional load, flow coefficient, and mass parameter and minimization of friction variable using genetic algorithm. The results using genetic algorithm are compared with sequential quadratic programming (SQP). The two grooved bearings in general have grooves placed at diametrically opposite directions. However, the optimum groove locations, arrived at in the present work, are not diametrically opposite.

Modified Equation

The Kozeny equation for the determination of surface areas by the gas-permeability method has been modified by the introduction of a second term, which takes the form of the Knudsen flow equation. This modified equation gives consistent results for the specific surface of a granular bed of fine particles with mean pressures of the flowing gas ranging from 2.6 cm. to almost atmospheric pressure. The results obtained from experimental data are in agreement with those calculated by direct visual and electron microscope counting.
