Bluff-body wakes play an important role in many fluid dynamics problems and engineering applications. This book gives an up-to-date account of recent results obtained in the study of bluff-body wakes. Experimental, theoretical and numerical approaches are compared. Topics of particular interest include hydrodynamic instability analyses, three-dimensional pattern formation problems, flow control methods, bifurcation analyses, numerical simulations and turbulence modelling. Recent conceptual advances made to describe nonlinear phenomena in general are put to the test on a classical problem in fundamental fluid mechanics, namely the wake structure generated behind a bluff object.
