摘要：In this paper we analyze the impact of the cavitation model on the numerical assessment of lubricated
journal bearings. We compare results using the classical Reynolds model and the p model proposed
by Elrod to x the lack of mass conservation of Reynolds' model. Both models give quite similar
predictions of load-carrying capacity and friction torque in non-starved conditions, making the Reynolds
model to be preferred for its better numerical behavior. Here we report on numerical comparisons of both
models in the presence of micro-textured bearing surfaces. We show that in the micro-textured situation
the Reynolds model largely underestimates the cavitated area, leading to signicant overestimation of
the friction torque. This dictates that only mass-conserving models should be used when dealing with
micro-textured bearings. Further, we provide numerical details on the algorithms used and apply them
to various cases of potential interest for industrial applications.
