Title: Dynamics of Non-reacting and Reacting Flows Past Bluff Bodies
Abstract: The unsteady fluid flow past a bluff body has been widely studied, particularly due to the distinctive flow features observed in the wake of the bluff body itself. The inherently complex nature of the problem has promoted several investigations over the past few decades. Apart from the non-reacting situation, bluff bodies have also been used in reacting flows as flame holders in various practical combustors. Recently, some researchers have reported practical scenarios where a different fluid is injected from ports on the bluff body on to the free stream, and there exist a few studies on the dynamics of such a flow scenario in both the non-reacting and reacting cases. The present chapter presents a brief review of the recent developments on flow past a bluff body in the non-reacting and reacting flow situations. The chapter also highlights the distinctive dynamics of flow past a bluff body when another fluid is injected from the bluff body itself. The effectiveness of the proper orthogonal decomposition technique to analyze the dynamics of flows past bluff bodies is also highlighted.
