This book was released on 1973 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: Swirling flow in a rotating tube is studied by flow visualization at a moderate Reynolds number, and its velocity field is measured by laser-Doppler anemometry. The tube has constant diameter, and approximately uniform initial rigid rotation of the flow is assured by passing the flow through a rotating plug of porous metal before it enters the test section. At moderate swirl values, an object mounted on the tube centerline causes a closed bubble to form upstream of the obstacle, with a clearly defined stagnation point on the axis, and recirculating flow inside the bubble. The bubble length grows upstream as the swirl is increased, until it breaks up into a Taylor column reaching all the way upstream and downstream at swirl values above a certain critical value. A vortex jump (in the sense of Benjamin) occurs downstream of the obstacle except when the Taylor column is present. Using a laser-Doppler anemometer, axial and swirl velocity profiles are obtained at several stations upstream and downstream of the bubble, and in and around the bubble.

Available in PDF, EPUB and Kindle. Book excerpt: Turbulence measurements with a Laser Doppler Velocimeter (LDV) using the dual scatter or differential Doppler mode have been made in a subsonic, fully developed channel flow. The measurements were made using only those light scattering particles occurring naturally in air. Results include mean velocity profiles, turbulence intensities, Reynolds stress distributions and a skewness measurement of the velocity distribution function across the channel. Statistical techniques were used to obtain the various turbulence parameters. Guidelines have been established for the amount of data needed to obtain results with a specified accuracy and confidence level. Measurements have also been made to determine the particle-size distribution. An aerodynamic means was used to determine the size distribution, in contrast to the usual optical procedures.

Available in PDF, EPUB and Kindle. Book excerpt: Increasing possibilities of computer-aided data processing have caused a new revival of optical techniques in many areas of mechanical and chemical en gineering. Optical methods have a long tradition in heat and mass transfer and in fluid dynamics. Global experimental information is not sufficient for developing constitution equations to describe complicated phenomena in fluid dynamics or in transfer processes by a computer program . Furthermore, a detailed insight with high local and temporal resolution into the thermo-and fluiddynamic situations is necessary. Sets of equations for computer program in thermo dynamics and fluid dynamics usually consist of two types of formulations: a first one derived from the conservation laws for mass, energy and momentum, and a second one mathematically modelling transport processes like laminar or turbulent diffusion. For reliably predicting the heat transfer, for example, the velocity and temperature field in the boundary layer must be known, or a physically realistic and widely valid correlation describing the turbulence must be avail able. For a better understanding of combustion processes it is necessary to know the local concentration and temperature just ahead of the flame and in the ignition zone.

Download or read book Laser Systems in Flow Measurement written by Tariq Durrani and published by Springer. This book was released on 1977 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is now well established that laser flow-measuring systems have important advantages over more conventional techniques both for industrial and laboratory applications. These fundamental advantages are indicated by the enormous research effort which has gone into their development over the last decade and by the number of commercial systems which have become available. Although the field is still developing, the most important theoretical results required for relating the system outputs to the fluid flow parameters have now been formulated and a book on the subject therefore seems timely. In the text we have tried to collect together the most important results both from our own papers and from publications by other authors and to present these in a concise and easily readable form. Emphasis has been placed on the fundamental theory and limitations associated with the various techniques rather than on detailed description of specific systems. We have also included a number of new results on areas such as photon counting in turbulent and periodic flows, frequency domain and time domain analysis of laser Doppler velocimeter signals, effect of background noise on system performance, and on cross-correlation techniques for diffusing flows.

Download or read book Field Test Results of a Laser Doppler Velocimeter and an Acoustic Doppler Wind Sounder written by Frederick J. Brousaides and published by . This book was released on 1978 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: A field test program was conducted to evaluate the potential of two indirect wind sensing techniques as possible support in a warm fog dispersal system. The sensors examined were a Laser Doppler Velocimeter and an Acoustic Doppler Wind Sounder. Data from these devices were correlated with measurements taken by anemometers mounted upon a 61-m meteorological tower. The average deviation of the Laser Doppler Velocimeter was + or - 1.0 m/sec in wind speed and + or - 7 deg in azimuth. Five-minute averaging periods were taken and four to six altitudes were scanned during each run. The average deviation of the Acoustic Doppler Wind Sounder for 5-min averages was + or - 0.9 m/sec in wind speed and + or - 13 deg in azimuth. In one protracted run using 10-min averages, the deviations were + or - 0.6 m/sec in wind speed and + or - 6 deg in azimuth.
