Notes:
A continuum model of the evolution of air ingestion and entrainment for open-endedsqueeze film dampers is proposed in this paper. Hydrodynamic lubrication theory is extended tolubrication with mixture of a Newtonian liquid and an ideal gas. The solution to the universalReynolds equation is determined numerically using a control volume method (Elrod algorithm) andthe forth-order Range-Kutta method. This method conserves mass throughout the computationaldomain including air ingestion and entrainment. Excellent agreement is found with the experimentalworks of Diaz and San Andrès for the squeeze film damper [1, 2]
