WebNear a solid boundary the flow has a distinct structure, called a boundary layer. The most important aspect of a boundary layer is that the velocity of the fluid goes to zero at the boundary. This is called the "no-slip" condition, i.e. the fluid velocity matches (has no slip relative to) the boundary velocity.
