Gradient boundary
Web2 days ago · Boundary Layer. Boundary layer is a region where viscous force is relatively high compared to inertia, force due to pressure gradient, gravitational or electromagnetic force. Viscous force appears when there is a velocity gradient in the flow. Velocity gradients occurs usually next to the walls, where the fluid takes the velocity of the wall ...
