Question

Is shed vortex can be modeled at vertical velocity?

(a) True

(b) False

The question was posed to me at a job interview.

My doubt stems from Prandtl’s Classical Lifting-Line Theory topic in chapter Flow over Airfoils over Finite Wing of Aerodynamics

Answer 1

Right choice is (a) True

Easy explanation: The shed vortex can be modeled as a vertical velocity distribution. The up wash and downwash induced by the shed vortex can be computed at each neighbor segment. This sideways influence up wash on the outboard, downwash on the in a board.
