The Computation of Hydrodynamic Lubrication Based on Computational Fluid Dynamics Approach

在分析雷诺方程求解流体润滑问题上的不足与局限性的基础上,给出了基于N-S方程的计算流体力学(CFD)求解流体润滑问题的方法。对CFD方法求解流体润滑问题的可行性进行了研究,给出了CFD方法求解流体润滑问题的一般流程、求解过程、数值计算实例,最后指出了CFD方法求解流体润滑问题时可能的发展趋势。

Since the limitation of Reynolds equation in lubrication, one way of computational fluid dynamics （UYD） approach which based on Navier-Stokes equation was advanced to solve lubrication questions. The suitability of CFD approach was discussed. The flow of using CFD approach to solve hydrodynamic lubrication was investigated. CFD approach was summarized, the application prospect of this approach in solving lubrication was put forward.
