3D Velocity Profile for Flow between Two Cylinders

This Demonstration simulates the solution of the Navier–Stokes equations for radially symmetric steady-state incompressible fluid flow between two long cylinders, with external constant pressure gradient. At the boundary conditions, the outer cylinder has zero velocity while the inner cylinder is moving with a constant velocity.
