I think that picture shows the distribution of downwash velocity at some distance behind the wing (10x wingspan), where the trailing vortex sheet has 'rolled up' into two discrete vortices. Would the distribution closer to the wing be more even
(i.e. closer to a constant downwash velocity across the span)?
