The theoretical research,design and calculation of dry gas seal is generally based on the assumption of laminar flow.However,as the sealing operating conditions gradually become highly parameterized and the process medium becomes multiphase,the fluid will be in a turbulent flow state under high parameter and extremely complex working conditions,and the traditional laminar flow theory will no longer be applicable.Therefore,the turbulent effect of lubricating gas should be considered in the theoretical design and research of dry gas seals.Three widely used turbulent lubrication models,namely Constantinescu model,Ng-Pan-Elrod model and Hirs model,were summarized,the theoretical basis and applicability of each model was described.The turbulent lubrication equation and its turbulent coefficient expression under different models were explained,and the research progress at home and abroad considering the influence of turbulence effects on the stability and dynamic performance of dry gas seals was reviewed.
