The Effects of Three-Dimensional Imposed 3-D Disturbances on Bluff-Body Near Wake Flows

Abstract

This experimental research effort focuses on the underlying three- dimensional flow structure in the near wake of a bluff body when subjected to imposed geometrical disturbances. We want to understand the effects of three dimensionality that are characterized by vortex splitting and looping and how they are related to other wake parameters such as base pressure shedding frequency, wake width and wake formation length.
