Annular flow between cylinder and cylinder for mechanical seal application

Taylor vortex flow If the gap between the inner cylinder and the outer cylinder is very narrow, as long as the Reynolds number has not reached the turning point of rotation, the flow state is always laminar. If the gap is large enough and the rotation speed reaches the critical speed, there will be a secondary (auxiliary) flow state of Taylor vortex flow. In mechanical seal applications, these vortices flow around the axis of rotation in a circular flow, which is about the height of the gap Twice. Taylor mathematically analyzed the critical rotation speed when the vortex was formed, and verified it through experiments, which marked the Taylor quasi number when the Taylor vortex appeared. 　　328.html,
