Question

Purpose of vortex method is ____________

(a) To reduce the dimensionality of aerodynamic model

(b) To increase the dimensionality of aerodynamic model

(c) To reduce the lift of aerodynamic model

(d) To increase the lift of aerodynamic model

The question was asked during an interview.

My question comes from The Vortex Sheet topic in division Incompressible Flow over Airfoils of Aerodynamics

Answer 1

Correct option is (a) To reduce the dimensionality of aerodynamic model

The explanation: Vortex method is extensively applied to reduce the dimensionality of these aerodynamic models based on the proper estimation of the strength and distribution of the vortices in the wake this condition can be readily applied to the flat plate or an airfoil with a cusped trailing edge were the flow will leave smoothly.
