Abstract
Surface texturing plays an important role to enhance the performance of the tribological components with increase in load carrying capacity and reduction in friction and wear. A numerical study of hydrodynamic lubrication of slider bearing with textured surface is reported. The optimization and comparison of single, double, four, 3600, 2700, 1800, 900 round cylindrical surface cavities are analyzed with incompressible fluid film in isothermal condition. The change in orientation of the surface cavities are studied with different texture parameters like height ratio, area density and dimple depth. The finite volume method is used to solve the Navier-Stokes equation with the help of ANSYS Fluent. It is concluded that 3600 round single cylindrical surface cavity achieves larger pressure and reduction in friction when the cavity is shifted towards the leading side of the bearing as compared to other surface cavities. It is also observed deeper and wider cavity cause a large reduction in the value of coefficient of friction.
