Vortex-dominated flows are in abundance in engineering applications and natural environment. Vortical structures influence not only the flow field but also have major implications on forces and moments experienced by objects as well as noise generated by them. If we can predict/infer the presence and characteristics of vortices, then we might be able to harness their potential to our benefit. In this talk, I will present experimental results from two case studies where vortical structures lead to detrimental performance in one and improved efficiency in the other. These examples come from varied application areas including flow past bluff bodies to underwater autonomous vehicles.
