| Summary: | A generalized form of Reynolds equation for two symmetrical surfaces is taken by considering velocity-slip at the bearing surfaces. This equation is applied to study the effects of velocity-slip and viscosity variation in squeeze film lubrication of hydro static step-seal. Expressions for the load capacity are studied theoretically for various parameters. The load capacity decreases due to slip. The Load Capacity increases due to the presence of high viscous layer near the surface and decreases due to low viscous layer and it has been shown that the load capacities of squeeze film bearings decrease and those of step seals increase with an increase in the step height. With a hydrostatic step seal, the load capacity increases as the flow behaviour index of the fluid increases. |
