Many studies have been performed on the impact of surface roughness on journal bearings, but there is still much to learn. Hydrodynamic lubrication has received far more attention than elastohydrodynamic lubrication. The effect of roughness and elastohydrodynamic lubrication on journal bearing cavitation will result in the lubricant and structural. This research will look into the effect of surface roughness on the pressure distribution, vapor volume fraction, and deformation of the journal bearing. The 2-way FSI approach, which is modeled with CFD, will be a helpful technique in this study. The simulation begins with the creation of a model in CAD and the determination of its geometry, meshing, phase definition, boundary conditions definition, and the determination of the Solution Method, the Solution Control, and the Iteration Process.The interaction of the lubrication fluid with the journal bearing's structure will be intriguing to see.It has been confirmed that as roughness increases, the pressure distribution, vapor volume fraction, von Mises stress, and deformation values decrease.
