Book excerpt: The behaviour of the trailing vortices of a Harvard aircraft used as the spraying vehicle during a set of experiments in aerial spraying over flat terrain for agricultural applications is discussed. The aircraft flew at a nominal altitude of 3 m (10 ft.) above ground at a speed of 56.7 m/s (110 knots). The stability and trajectory of a chosen element of the trailing vortices were measured by analyzing movie films taken by a ground-based camera and by a camera in a helicopter hovering at about 244 m (800 ft.) above the aircraft. The vortices decayed by core bursting in every case and the time to burst was usually in agreement with other published data for a light aircraft out of ground effect. The downwind vortex almost always burst before the upwind vortex and in most cases, both upwind and downwind vortices exhibited about the same amount of rebound even though the downwind vortex generally had a shorter lifetime. The classical inviscid theory for vortex descent was not a good model for the current experiments but it was able to predict with some success the lateral separation between the vortices when the aircraft wing tip height was arbitrarily reduced by a factor of 0.85. It was concluded that vortex core bursting and rebound must be included in any procedure for calculating aerial spray deposit on the ground.

Download or read book Fluid Vortices written by Sheldon Green and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 905 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fluid Vortices is a comprehensive, up-to-date, research-level overview covering all salient flows in which fluid vortices play a significant role. The various chapters have been written by specialists from North America, Europe and Asia, making for unsurpassed depth and breadth of coverage. Topics addressed include fundamental vortex flows (mixing layer vortices, vortex rings, wake vortices, vortex stability, etc.), industrial and environmental vortex flows (aero-propulsion system vortices, vortex-structure interaction, atmospheric vortices, computational methods with vortices, etc.), and multiphase vortex flows (free-surface effects, vortex cavitation, and bubble and particle interactions with vortices). The book can also be recommended as an advanced graduate-level supplementary textbook. The first nine chapters of the book are suitable for a one-term course; chapters 10--19 form the basis for a second one-term course.

Available in PDF, EPUB and Kindle. Book excerpt: This special volume contains the proceedings of the Symposium held on June 26, 1988 at Williamsburg, Virginia, in honor of Professor Maurice Holt on the occasion of his seventieth birthday. There were more than two dozen participants from eleven countries. They were either his past students or his colleagues whose careers crossed his at some point. The twenty-one papers in this volume are the written version of the presentations at this Symposium; they are mostly in the area of computational fluid dynamics (CFD), a field in which Professor Holt is a pioneer. These papers cover almost all aspects of CFD including numerical analysis, symbolic analysis, and grid genera tion. They cover diverse topics such as complex plume flows, shock waves and shock focussing, coronary circulation, free surface flows, direct containment heat ing in nuclear reactors, and uranium enrichment. There is also an article on the progress and future directions in CFD by one of the true experts in this area. In addition to CFD papers, there is an experimental paper on the flow of spherical glass beads in airflow in a 90° vertical-to-horizontal bend, as well as a historical paper on seventy years of fluid dynamic research at Aerodynamisches Institut at Aachen. It is worth pointing out that there is also an article on the simple fluid concept by a world-renowned authority on continuum mechanics.
