This book was released on 2018-07-03 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: In-flight flow visualization techniques used at the Dryden Flight Research Facility of NASA Ames Research Center (Ames-Dryden) and its predecessor organizations are described. Results from flight tests which visualized surface flows using flow cones, tufts, oil flows, liquid crystals, sublimating chemicals, and emitted fluids have been obtained. Off-surface flow visualization of vortical flow has been obtained from natural condensation and two methods using smoke generator systems. Recent results from flight tests at NASA Langley Research Center using a propylene glycol smoker and an infrared imager are also included. Results from photo-chase aircraft, onboard and postflight photography are presented. Fisher, David F. and Meyer, Robert R., Jr. Ames Research Center RTOP 505-68-71...

Download or read book Flow Visualization Workshop Report written by William C. Ragsdale and published by . This book was released on 1972 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: A workshop on flow visualization and flow measurement techniques was held at Silver Spring, Maryland, on 21 and 22 October 1971 and co-sponsored by the Naval Air Systems Command and the Naval Ordnance Laboratory. The objective of this meeting was to provide a forum for technical discussions on new and improved flow visualization and flow measurement techniques. Discussion of the application of new techniques to flow problems associated with turbo-machinery, aircraft and missiles was included. (Author).

Download or read book Flow Visualization Techniques And Examples written by Tee Tai Lim and published by World Scientific. This book was released on 2000-09-04 with total page 410 pages. Available in PDF, EPUB and Kindle. Book excerpt: Throughout history, flow visualization has been an important tool in fluid dynamics research. It has been used extensively in the fields of engineering, physics, medical science, meteorology, oceanography and sport aerodynamics, to name just a few. The importance of flow visualization led Professor F N M Brown (1971) of the University of Notre-Dame to comment, “… A man is not a dog to smell out each individual track, he is a man to see, and seeing, to analyze…” This statement encapsulates the importance of first visualizing the flow before proceeding with detailed measurement and mathematical modeling. In addition, there is a great deal of esthetic pleasure to be gained from seeing the results of flow visualization. This aspect of flow visualization reaches out to the general public: we are all familiar with the aspect of clouds in the sky, the trail of cigarette smoke, and the swirling patterns to be seen in rivers and seas.Unlike previous publications which concentrated mainly on the theoretical aspect of flow visualization, this book focuses on the techniques required to perform high quality flow visualization. It is aimed primarily at the practitioner of flow visualization studies. Obtaining good flow visualization results is, in many ways, more an art than a science, and experience plays a deciding role. Hence each chapter of this invaluable volume has been written by an expert in a particular technique./a

Download or read book Flow Visualization Studies of a Fin Protuberance Partially Immersed in a Turbulent Boundary Layer at Mach 5 written by Allen Edward Winkelmann and published by . This book was released on 1970 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: Various flow-visualization results are presented for a cylindrically blunted, unswept fin (yawed and unyawed) partially immersed in a turbulent boundary layer (delta approx. = 2.6 inches). The model, consisting of a fin-flat plate combination, was tested at a nominal Mach number of 5 and nominal free-stream Reynolds numbers per foot of 2800 000 and 7400 000. Azobenzene tests show regions of high heat transfer on the flat plate immediately upstream and downstream of the fin. Oil smear tests show in detail the surface shear directions and locations of separated flow which occur on the model. Schlieren and shadowgraph photographs indicate the complex shock wave structure which exists in front of the fin. A possible flow-field model is suggested to account for the observed flow patterns.
