Abstract: The diffusive and viscous leaks through a model spiral groove static ring gasket are studied analytically. This system is characterized by a transition from a leak through radial passages to ...

Abstract: The effects of lubricant film flow, pressurized and sheared between two parallel sinusoidal wavy surfaces in sliding motion is studied analytically. Results are presented using a flow factor ...

Abstract: In this paper a theoretical investigation is reported on the effect of surface roughness on the phenomenon of Leidenfrost-levitation of droplets above a hot surface. The problem is solved first ...
