...Mushrek A. Mahdi; Ahmed Waleed Hussein Purpose The purpose of this paper is to investigate the combined effect of wear and turbulence on the performance of a hydrodynamic journal bearing operating under Newtonian and couple stress fluids (CSF). Design/methodology/approach The analysis consists...

... affects the oil thickness and subsequently the pressure distribution. Moreover, the equilibrium point of the rotor, the dynamic coefficients of the bearing and the response of the system are affected as well. The onset and development of wear in plain hydrodynamic journal bearings under repeated stop...
