Oil film behaviour in hydrodynamic lubrication of journal bearing / Mohamad Ali Ahmad

This thesis presents an integrated investigation of various aspects of hydrodynamic lubrication in a journal bearing. Hydrodynamic journal bearings are critical power transmission components used to carry high loads in different machines applications. In machine design, it is essential to know the t...
