LoginIs thin sheet of intense vorticity is unstable at downstream?
(a) True
(b) False
This question was posed to me during an online exam.
My question is from Kelvin’s Circulation Theorem and the Starting Vortex in division Incompressible Flow over Airfoils of Aerodynamics
Aerodynamics Incompressible Flow over Airfoils in Aerodynamics 3 years ago
Correct answer is (a) True
To elaborate: As flow moves to the downstream, this THIN SHEET of intense vorticity is unstable, and it tends to roll up and form a picture SIMILAR to a point vortex. This vortex is called the STARTING vortex and is similar to the point vortex.
