The effect of isotropic roughness on the thermohydrodynamic solution of finite journal bearings

Thermohydrodynamic (THD) analysis of finite journal bearings with isotropic roughness is presented. A modified version of the Reynolds equation which includes surface roughness effects is solved using the Successive-overRelaxation method (SOR). 7he Swift-Stieber cavitation boundary condition was...
