The thermohydrodynamic (THD) performance of finite inclined-plane slider bearings is studied. The fluid film momentum, continuity, and energy equations are coupled to the heat-conduction equations for the bearing solids, and solved numerically. The effect of bearing geometry, oil type, and inlet temperature on bearing performance is shown. The manner in which environmental temperature and heat transfer considerations influence the fluid film behavior is studied.

Magneto Rheological

Magneto Rheological (MR) fluids are a class of smart materials where the shear stress is not directly proportional to rate of shear. The viscosity of fluid changes as magnetic field changes and hence this phenomenon is very useful in bearing-rotor system for attenuating the vibrations. In the present study the application of MR fluid as lubricant instead of Newtonian fluid in the journal bearing is explored through steady state, dynamic characteristics and stability. MR fluid film has been modeled as per Bingham rheological model. FEM with three node triangular elements has been used to solve the Reynolds equation both for the Newtonian fluid film and MR fluid film. The results show the load carrying capacity in the case of MR fluid journal bearing is higher than that of using the Newtonian fluid. The load carrying capacity increases with the increasing magnetic field for all eccentricity ratios. The results also show better stability of the bearing using MR fluid at higher eccentricity ratios. The unbalance response of the rotor mounted on the journal bearing using MR fluid is also estimated to be lower than that of with the Newtonian fluid.

Energy Equations

The thermoelastohydrodynamic (TEHD) behavior of a finite inclined-plane slider bearing is studied. The fluid film momentum, continuity, and energy equations are coupled to the heat conduction equations and the elasticity equations of the solid, and solved numerically. The elastic and thermal distortions of the solid as well as the variation of fluid properties with temperature are considered in the analysis. Several models for the bearing solids are treated.
