Cfd Investigation Of Oil-Free Granular Lubrication

This study presents an advanced theoretical modeling methodology and simulation procedure to evaluate the performance of granular lubrication. The computational approach utilizes the Euler-Eulerian multiphase flow model based on the solid kinetic theory in a 3D Computational Fluid Dynamics (CFD) framework. The predictions of the CFD model are verified by available experimental data, and a parametric study is presented to assess the influence of critical input parameters. The parametric study provides valuable information for a suitable and efficient granular lubricating system design.
