Large Scale Simulation of Fluid Flows for Lubrication of Rough Surfaces

Abstract

This paper presents a novel method to compute the lubricant pressure distribution between a rough and a smooth surface in relative motion. The originality of this method is to combine a deterministic approach for the large scales and a stochastic model for the small scales of the problem. As a result, the new method allows a significant mesh reduction while maintaining an accurate prediction of the generated load.
