Effects of Three-Dimensional Imposed Disturbance on Bluff-Body Near Wake Flows

Abstract

The long term goals of the project are: (1) Mechanics of the development, modification and control of the near wake behind a nominally two- dimensional bluff body. (2) Understanding the effects of controlled three- dimensional disturbance on the region of absolute instability. Comparison of classical bluff body wake flow entrainment mechanisms by Gerrard with instability concepts. (3) Implication of the imposed disturbances for cut-off blunt trailing edge (BB) vis a vis a circular cylinder (CC). (4) Mechanics of uniform and nonuniform flow past a circular cylinder with a free-end.
