Flow factors for non-Gaussian roughness in hydrodynamic lubrication: an analytical interpolation

摘要

By extending the stochastic averaging techniques for lubricated rough surface contacts, as developed by Christensen and Tønder, a simple analytical transformation is derived to obtain the pressure flow factors for a non-Gaussian roughness whenever the corresponding Gaussian factors are known. The method is compared with results from numerical solutions available in the literature and it shows good agreement. [PUBLICATION ABSTRACT]
