| Summary: | account the convection and dissipation in axial and An approach for three dimensional Therinohydrodyiiamic analysis of multi-lobed journal bearings is presented. The and realistic temperature distribution, three dimensional associated boundary conditions. In order to obtain a stable cavitation boundary and thermal cavitation model is applied circumferential directions. Heat conduction through the coefficients of bearing using variable viscosity model are Comparison is also irlade between results obtained using derived and compared to isoviscous results-Thermohydrodynamic direction is considered. Variation of viscosity in all three directions is considered. A finite element method is used to distribution in the axial and circumferential directions. finite element upwinding technique is developed and fluid film ill axial, circumferential and cross-film generalized Reynolds equation solution yields the Dressure in that region. Location and magnitudes of maximum incorporated whenever the convective term is dominant. model. more realistic three dimensional boundary conditions on the obtained and compared to existing data in literature. optimal and full upwinding versus no upwinding. Dynamic Reynolds boundary condition is used to determine the simulation of multi-lobed journal bearings is presented using solve the associated partial differential equations and the temperature in the bearing and the pressure profiles are The energy equation is three dimensional and takes into |
