AbstractThis paperpresents numerical solution to the pressure distribution of a fluid in ahydrodynamically lubricated journal bearing using the classical Reynoldsequation that models the effect of side or end leakage i.e., there is flow inthe z-direction in bearings. The finite element method was used to analyze theflow. Two dimensional interpolation functions were used in the modelling anddiscretization of the domain of analysis. The result obtained from this research shows that the pressure increasesfrom the ambient pressure which is taken to be zero at an angular displacementof and increasessignificantly till . At this point, thepressure becomes maximum. Thereafter, it begins to drop until it gets to where the pressurebecomes the same as the ambient pressure. From this point onward, we begin toexperience negative pressure. The negative pressures in this regard are thosethat are below the ambient pressure.
