Fluid flow state of mechanical seal

In fluid mechanical seals, many properties and parameters depend on the flow state of the leaking fluid. Due to the wide working range of the mechanical seal, a variety of flow states may occur in it. Due to space limitations, only the most common flow states are discussed here.

When judging the flow state of the leaking fluid, some similar criteria are often used, such as the Reynolds number, Mach number, Taylor number, Euler number, etc. used for simple flow problems. However, the flow of some leaking fluids is closely related to heat transfer, and other similar criteria are also used, such as the Plant's criterion, the Nusselt criterion, the Beck column criterion, and the Pio criterion, to distinguish the heat transfer flow state.　　318.html,
