Is thin strips of vorticity are unstable to disturbances and tend to roll up?(a) False(b) TrueThe question was asked in homework.Enquiry is from The Vortex Filament, Biot-Savart Law, Helmholtz Theorem topic in portion Flow over Airfoils over Finite Wing of Aerodynamics

Answer»

Right option is (b) True

The explanation is: Vortex filament is well known that thin strip of VORTICITY are unstable to disturbance and tend to roll up. Here we test this using our MODEL, we study TWO cases a parabolic vortex filament and a CIRCULAR vortex filament.
