NUMERICAL INVESTIGATION ON THE INFLUENCE OF SURFACE TEXTURE HYDRODYNAMIC JOURNAL BEARING USING CFD
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 5, Issue 7
Abstract
Thermohydrodynamic (THD) analysis should therefore be carried out to obtain the realistic performance characteristics of the bearing. So many researchers have been done in this field. Most of these analyses used two dimensional energy equation to find the temperature distribution in the fluid film by neglecting the temperature variation in the axial direction and two dimensional Reynolds equation was used to obtain pressure distribution in the lubricant flow by neglecting the pressure variation across the film thickness. In this paper a numerical approach which can accurately predict the performance characteristics of a surface textured (grooving) journal bearing have been presented. In this present investigation, some parameters are changed like; groove diameter, number of groove or pattern. After analysis the results are validated in some good literature which mentioned in reference. The three dimensional momentum equations and the continuity equations governing the flow field in the positive pressure fluid film region in the clearance space of the finite bearing are used to obtain velocity and pressure field in the fluid flow. Three dimensional energy equations is used to obtain the temperature distribution in the fluid film. The solutions of the lubricant flow and thermal equations are obtained using a CFD software Fluent.
