Abstract: The flow field within the lubricating film of a rotating shaft lip seal containing microundulations is analyzed numerically. The results demonstrate that the action of the microundulations can ...

Abstract: Previous numerical simulations and experimental observations have shown that the meniscus in a rotary lip seal will be ingested into the sealing zone when the shaft speed exceeds a critical ...

Abstract: A model of the non-leaking equilibrium behavior of the lip seal has been developed. It consists of an elastohydrodynamic model of the lubricating film and a simplified model of the meniscus ...

Abstract: A stable and convergent computational method is presented for the calculation of the flow field in the film between the faces of a wavy mechanical seal. The method is particularly useful for ...

Abstract: An elastohydrodynamic analysis of a rotary lip seal containing microundulations, incorporating both the fluid mechanics of the lubricating film and the elastic behavior of the lip, has been ...

Abstract: A mathematical model that predicts the transient behavior of gas or liquid lubricated hydrostatic mechanical seals has been developed. The analysis includes an evaluation of the fluid, contact, ...
