Available in PDF, EPUB and Kindle. Book excerpt: The primary objective of this study was the characterization of the three-dimensional longitudinal vortices found in the wake of a circular cylinder. Using Particle Image Velocimetry (PIV) full instantaneous velocity fields were obtained in the transverse plane containing the cylinder. Footprints of the longitudinal vortices were identified, showing up as counter-rotating pairs. It appears that these vortices are embedded between, and locked to, the Karman vortices. From measured peak vorticity fields, it is clear that the longitudinal vortices are being stretched by the Karman vortices.

Available in PDF, EPUB and Kindle. Book excerpt: Over the last decade, there has been much work carried out to understand three-dimensional effects at low Reynolds numbers (Re) in the wake of bluff bodies, yielding the reaction that end effects can influence the vortex shedding across large spanwise lengths. Wake patterns such as parallel shedding, oblique shedding, cellular shedding, transient patterns, such as 'phase shocks' and 'phase expansions', as well as the existence of large-scale 'vortex dislocations', have been investigated, aspects of this research being spearheaded by me studies at Cornell under the above Contract. In particular, we have discovered a new mechanism for oblique wave resonance in the far wake. We have found a means to control the near wake by using suction at the spanwise ends of a body, which has enabled much more precise phenomena to be investigated including the critical conditions for turbulence inception, and a careful study of 3-D wake transition. We have combined our research at Cornell with studies by Dr. Peter Monkewitz at Ecole Polytechnique, Lausanne, who has effectively laid much of the foundation of the description of these near wake patterns in terms of a Guinzburg-Landau equation. For example, the now transient phenomenon known as a 'phase expansion' has been found to be directly analogous to a Prandtl-Meyer expansion found in gas dynamics. Clearly, the work under the support of the ONR has led to a surprisingly rich new understanding of three-dimensional effects in nominally two-dimensional wake flows.

Available in PDF, EPUB and Kindle. Book excerpt: We wish to achieve a better understanding of the underlying three- dimensional flow structure in the near wake of a bluff body when subjected to imposed geometrical disturbances. We want to understand the effects of three dimensionality that are characterized by vortex splitting and looping and how they are related to other wake such as base pressure shedding frequency, wake width and wake formation length.
