Abstract

This paper presents thermohydrodynamic solutions for a finite-width journal bearing withsingle axial groove on the crown by considering turbulent effects in lubricant film.Appropriate governing equations and boundary conditions are used for the fluid flow andheat transfer process occurring in finite full journal bearings. A general computerprogram is developed to numerically solve the set of governing equations. Results areprovided for THD characteristics of journal bearing in terms of Reynolds number, clearanceratio and eccentricity ratio. Good agreement with published experimental results wasachieved. The results indicate that the bearing temperature field and pressure field areconsiderably influenced by the journal bearing parameters.
