bound vortex मीनिंग इन हिंदी

This bound vortex then moves across the wing and, in the clap, acts as the starting vortex for the other wing.
In this view, the trailing vortex is a continuation of the " wing-bound vortex " inherent to the lift generation.
The vorticity in the starting vortex is matched by the vorticity in the bound vortex in the airfoil, in accordance with Kelvin's circulation theorem.
As the vorticity in the starting vortex progressively increases the vorticity in the bound vortex also progressively increases and causes the flow over the topside of the airfoil to increase in speed.
In this model the wing vorticity is modelled by a bound vortex of constant circulation, travelling with the wing, and two trailing wingtip vortices, therefore having a shape vaguely reminiscent of a horseshoe.
