This analysis is based on the numerical solution of three-dimensional energy equation coupled with Reynolds equation and the heat conduction equation in the journal bearing. Reynolds equation for the pressure distribution and the energy equation for the temperature distribution were used for this analysis. Finite element method was used to solve the Reynolds equation. By solving the generalized Reynolds equation, hydrodynamic pressure was found out. Finite difference method was used for predicting temperature distribution in journal bearing. The Fourier heat conduction equation in the non-dimensional cylindrical coordinate has been adopted for finding the temperature distribution in the bush. The temperature distribution along axial direction of the journal has been found out using a steady-state unidirectional heat conduction equation. http://pubs.sciepub.com/ajme/2/6/4/ajme-2-6-4.pdf hydrodynamic journal bearings Reynolds equation thermohydrodynamic analysis viscosity-temperature equation
