Improve Journal Bearing Design Using Numerical Method
Computational Fluid Dynamics (CFD) was used to study the force direction and magnitude of 2D journal bearing and tapered gap, also the load of 3D journal bearing at different eccentric ratio was studied using numerical method. All numerical simulation results were compared with theoretical analysis result, theoretical solution result and other available data from reference. The comparisons show good match between numerical simulation results and others. This paper had validated the reliability and accuracy of CFD which could be used to study the lubrication and oil film status for journal bearing with the gap less than 0.2mm and provide a sold foundation for CFD to be used for optimal design for journal bearing.
