1.	Is vortex filament is a very thin strip?(a) True(b) FalseThe question was posed to me in class test.Origin of the question is The Vortex Filament, Biot-Savart Law, Helmholtz Theorem in section Flow over Airfoils over Finite Wing of Aerodynamics
Answer» Right ANSWER is (a) True To explain: A VORTEX filament is a very thin strip of VORTICITY in x-y plane. The small thickness assumption will be USED to characterize the filament by its center line curve. Mass conservation and material transport of vorticity are used to describe variation in local thickness and vorticity.
