Turbulence Measurements with a Laser Doppler Velocimeter
Author: William Joseph Yanta
Publisher:
ISBN:
Category : Laser Doppler velocimeter
Languages : en
Pages : 104
Book Description
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.

Laser Systems in Flow Measurement
Author: Tariq Durrani
Publisher: Springer
ISBN:
Category : Science
Languages : en
Pages : 316
Book Description
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.

The Use of a Laser Doppler Velocimeter in Supersonic Flow
Author: William Joseph Yanta
Publisher:
ISBN:
Category : Aerodynamics, Supersonic
Languages : en
Pages : 64
Book Description
Results are presented for an experimental program which investigated the application of an LDV technique in supersonic flows. This paper presents an analysis of the behavior of light-scattering particles in rapidly accelerating or shock decelerated flows, an evaluation of particle production techniques and the results of several velocity measurements. Measurements included the velocity distribution along the nozzle centerline and flow over a diamond airfoil in a Mach 3 tunnel and velocity profiles for a turbulent boundary layer in a Mach 4.8 facility. It is demonstrated that LDV measurements can be made consistently with errors of less than five percent if the particle lag is considered. (Author).
