STUDY ON THE PERFORMANCE OF JOURNAL BEARING IN TURBULENT REGIME WITH THE COMBINED REYNOLDS STRESS MODEL

Abstract

Abstract: More and more journal bearings operate in turbulent regime in modern turbine machinery. The advanced combined Reynolds stress turbulent lubrication model is used to analyse the perforance of journal bearing. The database of turbulent lubrication parameters is established to improved the application of the combined Reynolds stress model in engineering more conveniently. The study results have good agreement with existing experimental measurements. And the effects of operating conditions on bearings’ turbulent performance are discussed.

Key words: Combined turbulent lubrication theory, Journal bearing
