Abstract: A closed-form average lubrication equation for thin film grain flow with the effects of surface roughness is derived. This equation is based on Haff’s grain flow theory and also the flow ...

Abstract: This paper analyzes the performance of hydrodynamic journal bearings by applying the control-volume method to solve the average lubrication equation for grain flow. The grain characteristics, ...

Abstract: Previous work by this group on an average lubrication equation for grain flow with roughness effects is extended to include grain-grain collision elasticity ranging from perfectly elastic to ...
