Modelling of Reverse Flows in a Mechanical Seal
The present paper describes a two-phase flow model used to study backward pumping of the low pressure fluid in the sealing interface of a mechanical seal. The Reynolds equation for a homogeneous mixture is solved as well as a transport equation used to determine the ratio of both fluids at each poin...
