Bluff-body wakes play an important role in many fluid dynamics problems and engineering applications. This book gives and up-to-date account of recent results obtained in the study of bluff-body wakes. Experimental, theoretical and numerical approaches are all comprehensively covered and compared. Topics of particular interest include hydrodynamic instability analyses, three-dimensional pattern formation problems, flow control methods, bifurcation analyses, numerical simulations and turbulence modelling. The main originality of thisvolume is that 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.

Using an experimental-numerical integrated approach, flow around and mean pressure fields on a blunt-based flat plate and a downstream circular cylinder in tandem and staggered arrangements have been investigated. The investigation focuses on the effect of a wide range of horizontal and vertical spacings between the plate and the cylinder, on the flow and the associated mean pressure distributions. With different cross-stream length scales, and relatively thicker boundary layers of the upstTeam plate, the plate-cylinder arrangement offers a unique configuration that has not been disclosed before. The experimental part of the study reveals that, similar to that observed for equal diameter cylinders, which has received the most research attention in the related literature, a critical spacing exists. For horizontal spacings smaller than the critical, formation of vortices in front of the downstream cylinder is inhibited. However, flow configuration before the critical spacing is found to be drastically different than those for the circular cylinders. It has been demonstrated here that, the critical spacing of the tandem arrangement is valid for the staggered arrangements as well. That spacing marks the boundary of a region on either side of which different flow interferences take place for both tandem and the staggered arrangements. Experimental study also reveals the variation with respect to spacing of the mean pressure distributions on surfaces of the trailing-end of the plate. The experimental part provides not only a unique set of data, but also a basis for comparison for the numerical part of the study. In the numerical part, two different types of the discrete vortex method has been utilized. Firstly, an inviscid, Lagrangian approach allowed representation of boundary layers separated from the upstream plate by practically zero thickness rows of discrete vortices. The approach is original in combining the conformal-mapping image and the vortex-singularity-distribution techniques for representation of plate and the cylinder surfaces respectively. Secondly, a Lagrangian-Eulerian viscous discrete vortex method is used. Utilization of panel representation of body surfaces along with overlapping rectangular grids, allowed development of a computer code for laminar, two dimensional flow calculation around bodies of arbitrary geometry and number. Both parts of the numerical study could predict number of flow features, implied by the xnean pressure distributions in their experimental counterpart. With a realistic representation of the thick boundary layers of the plate, the viscous method I correctly predicted the experimentally found critical spacing, and, with its clear images of flow evolution, contributed significantly to the understanding of wake interference as function of the distance between the bodies. An extensive comparison of the measured and calculated mean distributions as function of the spacing was made. It has been shown that the drag force acting on the cylinder is primarily dependent on the pressure difference between both ends of the cylinder.
