Abstract

Bluff bodies form ubiquitous components of many engineered structures. They are often exposed to turbulent flows, and the subsequent shedding of vortices gives rise to aerodynamic forces with large fluctuating components. As a result, significant oscillations are induced, which can lead to resonances and structural fatigue. To obviate these deleterious effects passive flow control mechanisms can be incorporated into the design of bluff bodies. However, to ensure the designs are effective and safe it is essential to understand and anticipate the behavior of the turbulent flows around bluff bodies.
