Theoretical hydrodynamic vortex behaviour both the free and forced vortex behaviours cannot prevail in a real fluid as the velocity will approach infinity with increasing or decreasing radius for the force and free vortex behaviours respectively. In the most fundamental terms ,if i were to talk about a free vortex in two dimensions ,the flow becomes rotational at r=0 at the center which is a singularity and every where else the flow is ir-rotational take the curl of velocity function and see yourself. Such a vortex is called a free vortex a good and familiar example is that of a bath tub vortex contrary to this we have a forced vortex which behaves like a solid body these have their velocity given by , with a zero velocity at the origin.
