Boundary layer (surface layer) flow of mechanical seal

In the case of large Reynolds number, the mechanical seal applied to the fluid flowing through the object can usually be divided into two flow areas:

(1) A very thin flow area adjacent to the surface of the object, called the boundary layer (the boundary layer). The influence of fluid viscosity and heat conduction in the boundary layer is more significant, and the resistance and heat transfer of the object must be considered Flow in the boundary layer;

(2) Outside the boundary layer is the potential flow area of u200bu200ban ideal fluid with negligible viscous effects and heat conduction, often called external potential flow.　　322.html,
