CFD analysis of thin film lubricated journal bearing

The three dimensional CFD analysis were investigated regarding the performance characteristics of a thin film lubricated journal bearing. In the existing literature, several numerical analyses had been reported. Most of these analyses used two dimensional Reynolds equations to find the pressure dist...
