In the present study, a computational investigation of thermohydrodynamic lubrication in pivoted-pad thrust bearings exhibiting different types of surface treatment is presented. Five different types of pivoted-pad thrust bearings are cross-evaluated for operation at different combinations of thrust load and rotational speed: (a) a pocket bearing, (b) a bearing with circumferential grooves, (c) a...
Hydrophobic surfaces, enabling flow slip past a solid boundary, can be effective for passive flow control applications. In the present study, a computational investigation of flow past a circular cylinder with slip conditions is performed, at low values of Reynolds number, Re. Slip is modeled based on the Navier model. When slip conditions are applied on the entire cylinder surface, the present results...
