Comment on the Loss of Vorticity in the Near Wake of Bluff BodiesSource: Journal of Fluids Engineering:;1989:;volume( 111 ):;issue: 001::page 104Author:M. M. Zdravkovich

Abstract: Fage and his co-workers [1,2] made a remarkable discovery in the 20’s that only half of the vorticity generated by bluff bodies remained concentrated in shed vortices. This belated comment reconsiders Fage’s method of “loss” calculation by examining nonlinear effects. The ignored effect of three dimensional distortion of vortex filaments before roll up might be another important cause for the “apparent” loss of vorticity.
