Download or read book Optical Techniques for Flow Visualization and Flow Field Measurements in Aircraft Turbomachinery written by Walter G. Alwang. This book was released on 1970. Available in PDF, EPUB and Kindle. Book excerpt: In the program two new optical methods of flow measurement were evaluated for eventual use in aircraft turbine engines. The methods studied were: holographic interferometry for visualization of flow and laser doppler velocimetry (LDV) for pointwise measurement of velocity. Prototype instruments of each type were built and tested in measurements on a supersonic cascade. It was found that double-pulse diffuse-background holographic interferometry can disclose the position of moving density gradients such as blade shocks. The LDV system, a dual beam, dual scatter system capable of both forward and back scatter operation, was found to be effective in measuring mean velocity and turbulence intensity. Capabilities and limitations of both instruments were assessed and requirements for internal measurements in turbomachinery determined. In general, it was concluded that the equipment developed is ready for application in turbine engines. (Author).

Download or read book Flow Visualization Workshop Report written by William C. Ragsdale. This book was released on 1972. 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).

Book Synopsis The Particle Image Velocimetry by : Giovanna Cavazzini

Download or read book The Particle Image Velocimetry written by Giovanna Cavazzini. This book was released on 2012-05-23. Available in PDF, EPUB and Kindle. Book excerpt: The Particle Image Velocimetry is undoubtedly one of the most important technique in Fluid-dynamics since it allows to obtain a direct and instantaneous visualization of the flow field in a non-intrusive way. This innovative technique spreads in a wide number of research fields, from aerodynamics to medicine, from biology to turbulence researches, from aerodynamics to combustion processes. The book is aimed at presenting the PIV technique and its wide range of possible applications so as to provide a reference for researchers who intended to exploit this innovative technique in their research fields. Several aspects and possible problems in the analysis of large- and micro-scale turbulent phenomena, two-phase flows and polymer melts, combustion processes and turbo-machinery flow fields, internal waves and river/ocean flows were considered.
