Abstract

The main purpose of this study is to compare the flow pattern and pressure distribution in journal bearing for different groove using Computational Fluid Dynamics (CFD). The groove types selected in this study are plain, wave, and rectangular. Operating condition of the system such as lubricant type, journal bearing ratio (L/d) and operating speed (N) are fixed respectively. Computational Fluid Dynamics (CFD) will be used to model the flow of journal bearing with different groove types. Navier-Stokes equations will be solved under unsteady conditions with the ANSYS FLUENT software. A 3-dimensional geometry is used to model the bearing, and the modeling will be created using 3D CAD design software SOLIDWORK. By performing numerical solution to this study, the flow pattern and pressure distribution profile for different groove type of journal bearing will be outlined. The results obtained are found to be the same agreement as previous studies. The results show same pattern for pressure profile for each journal bearing studied with wave-grooved journal bearing having the lowest pressure profile amongst other journal bearing
