The characteristics of mechanical face seals operating with hydrodynamic films containing gas cavities were studied. Solutions to Reynolds’ equation for hydrodynamic lubrication were obtained using both the short bearing approximation and numerical iterative methods. These two methods of solution satisfy continuity of flow throughout the seal film. Leakage rates and seal hydrodynamic loads were calculated. Some computed cavity shapes are also given.
