vUsing the characteristics of temperature dependence of liquid viscosity, possibility of control and improvement of static characteristics of hydrodynamic bearings is examined numerically. The simplified thermohydrodynamic lubrication (THL) model based on the Reynolds equation on the assumption of constant viscosity across the film is derived. The calculation is performed for inclined plane and tapered land bearings. The bearing geometry and temperature distributions are given by the parameters. When the inlet zone of the bearings is relatively cooled, the hydrodynamic pressure becomes high, the load-carrying capacity increases, and the friction coefficient decreases, but the side leakage hardly changes. The behaviors may contribute to enhance the static characteristics of hydrodynamic bearings.
