Flow mode of mechanical seal application

Regarding the flow pattern of mechanical seal applications, Kaye and Elgar have observed that when the rotation speed starts to increase from a critical value, Taylor vortices keep their shape unchanged until the rotation speed increases To a specific value. It can be observed that the formation of Taylor vortex is completely different from the formation of turbulence. When the rotational speed of the inner cylinder increases to a large value, the flow in the annulus becomes turbulent, and the vortex is superimposed on the turbulent fluctuation. If the rotation speed is further increased, it can be observed that the Taylor vortex is first distorted and then disappears completely, leaving only pure turbulent flow.

These flow patterns depend on the rotation speed of the inner cylinder and the average axial velocity.　　329.html,
