【Abstract】 The advanced combined Reynolds stress turbulent lubrication model is used to analyze the performance of plain seal. The database of turbulent lubrication parameters is established to resolve the numerical problem of the combined Reynolds stress model used in engineering. The results based on the model are in good agreement with that based on existing measurements. Thus the combined Reynolds stress turbulent lubrication model can well be used to describe the turbulent characteristics of plain seal.更多还原
