In this paper, the average lubrication equation for grain flow is solved using a control volume method to analyze the performance of hydrodynamic journal bearings. The grain particle size effect was investigated. The nondimensional load and friction coefficient are demonstrated in terms of eccentricity ratios under various diameter-to-width ratios. The results demonstrate the performance of powdered lubricated journal bearings, and also accord with the results experimented by Heshmat and Brewe.
