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.
