During the formation of starting vortex, for an airfoil starting from rest, which is the correct sequence of events? (TE: Trailing Edge)

During the formation of starting vortex, for an airfoil starting from rest, which is the correct sequence of events? (TE: Trailing Edge) Correct Answer Flow starts to curl at the TE > Velocity becomes infinite at the TE > High velocity gradient formed at TE which is pushed downstream > Unstable vortex sheet formed due to very high vorticity > Unstable vortex sheet curls to form point vortex

As the motion starts, the Kutta theorem starts enforcing itself due to which flow starts curling at the trailing edge and the high velocity gradient formed is pushed downwards so that the flow leaves the trailing edge smoothly. Then as the vortex sheet formed due to high velocity and consequently high vorticity is unstable, it curls itself to form what is called the starting vortex.
