A previously developed dynamic model for two-phase face seals is extended to include turbulent flow. Thermal transients over the entire range of laminar and turbulent flow are considered for both parallel and tapered geometries. Inlet losses and choking are accounted for in the turbulent regime. Axial responses to perturbations from equilibrium are examined, and general criteria are discussed for predicting stable, unstable and bistable seal operation.
