A hydrodynamic model is used to determine the generated pressure distribution within
the seal-shaft contact. Pertinent statistical parameters are selected to distinguish
between the various shaft surface topographies, which can contribute to an effectively sealed conjunction. Results obtained from the hydrodynamic model shows
the creation of multiple cavitated regions caused by the deep valleys. This leads to
thinner film thickness on the surface plateau and therefore lower predicted leakage
rates. The distribution of peaks and valleys is shown to be a factor in differentiating
contact performance.
