Abstract
A gaseous cavitation model, considering probable non-equilibrium dissolution effects in thrust bearings with hydrodynamic lubrication, is proposed. The model is a generalization of physical background of an equilibrium dissolution model upon Bunsen solubility. Utilizing and developing original conception of solubility, the rate of gas absorption or release process is modeled to be related to local variables. A simplified formulation of the non-equilibrium model is also derived adopting the approximation of quasi-one-dimensional flow for specific situations. The model is applied to thrust bearings with groove-land type, to preliminarily explore the effects of limited absorption rate on their performance and flow characteristics.
