No-slip condition

The no-slip condition in fluid mechanics says that, for viscous flows, the flow velocity of the fluid at a solid surface is always zero. This is the case with all real currents.

For potential flow, the no-slip condition does not apply, because potential flows are not subject to friction, ie it is modeled here is that no viscosity is present.

The no-slip condition is a prerequisite for the formation of boundary layers in the near-wall areas.

In the German -speaking world, the no-slip condition is often referred to with the English no-slip.
