... with different angles of journal misalignment and surface roughness, and considering oil VPR and thermal effect, were calculated based on the generalized Reynolds equation, energy equation, and solid heat conduction equation. The results show that the oil VPR and surface roughness have a significant effect...

... energy is carried away by the gas film flow leaving the bearing through its axial edges plus 12% convected naturally at the back of the top foil. The amount of heat conducted into the bearing cartridge and shaft adds to 31%. With an outer cooling flow stream, there is only 11.2% of heat advected...

... equation used considers the effects of heat conduction and convection, viscous heating, and the heat of evaporation. The developed method has been applied to a series of cases of lubricated metal-on-metal line contact with an entrainment velocity of u ent = 2.5 m ∕ s , viscosities η 0 = [ 0.01 , 1 ] Pa s...

... for the oil film. The Fourier series approximates the instantaneous temperature fields in the solid boundary layers. In this way, the mean heat flux that passes into the solid can be computed and a steady-state heat conduction equation can be used to obtain thermal fields inside the solids. Finally, solving...

...Jen Fin Lin; Jung Ching Chung; Jeng Wei Chen; Ta Chuan Liu The three-dimensional hyperbolic heat conduction equation is solved to obtain the analytical solution of the temperature rise at the contact area between an asperity and a moving smooth flat. The present analyses can provide an efficient...

... element analysis of heat conduction and thermal deformation is performed to determine the viscosity and clearance of hydrodynamic bearings at elevated temperature until the temperature in the bearing area converges. The proposed method is verified by comparing the calculated temperature with the measured...
