Book excerpt: Laser holographic interferometry was applied to the measurement of density profiles of two-dimensional planar turbulent boundary layers on the wall of the Acoustic Research Tunnel (ART) at the Arnold Engineering Development Center (AEDC). Holograms were produced at Mach numbers 0.50 and 0.65 by the finite fringe, single-plate, dual-exposure method. The reconstructed image from this type of hologram contains fringes that are shifted relative to a reference fringe by an amount that is proportional to the difference in the densities at the two points. Therefore, it was possible to determine the density profiles by measuring the fringe shifts appearing in the reconstructed images. The results of two velocity-temperature relations are presented, and compared to data obtained by pitot, hot-wire, and split-film probes. A description of the experimental facility, hardware for data acquisition, data reduction methods, and a discussion of the problems encountered in the holographic interferometry technique are presented.

Book excerpt: Holographic interferometry was successfully applied to a large-scale wind tunel (40-cm x 40-cm test section) experiment on a three-dimensional flow field. The laser interferometer was set up in a schlieren bench with a pulsed-ruby laser as the light source. Both the object beam and the reference beam were collimated. The conventional double-exposure, off-axis operation was used to produce interferograms...

Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and dis seminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the ac tivity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volume were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 22 (thesis year 1977) a total of 10,658 theses titles from 28 Canadian and 227 United States universities. We are sure that this broader base for theses titles reported will greatly enhance the value of this important annual reference work. While Volume 22 reports theses submitted in 1977, on occasion, certain universities do report theses submitted in previous years but not reported at the time.

This book was released on 1978 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: Experiments have been carried out to test the accuracy of laser-Doppler instrumentation for measurement of Reynolds stresses in turbulent boundary layers in supersonic flow. Two facilities were used to study flow at constant pressure. In one facility, data were obtained on a flat plate at M sub e = 0.1, with Re sub Theta up to 8,000. In the other, data were obtained on an adiabatic nozzle wall at M sub e = 0.6, 0.8, 1.0, 1.3, and 2.2, with the Re sub Theta = 23,000 and 40,000. This report is limited to a description of the mean flow as observed using Pitot-tube, Preston-tube, and floating-element instrumentation. Emphasis is on the use of similarity laws with Van Driest scaling and on the inference of the shearing-stress profile and the normal velocity component from the equations of mean motion. The experimental data are tabulated.

Available in PDF, EPUB and Kindle. Book excerpt: The book presents the principles and methods of holographic interferometry - a coherent-optical measurement technique for deformation and stress analysis, for the determination of refractive-index distributions, or applied to non-destructive testing. Emphasis of the book is on the quantitative computer-aided evaluation of the holographic interferograms. Based upon wave-optics the evaluation methods, their implementation in computer-algorithms, and their applications in engineering are described.

Available in PDF, EPUB and Kindle. Book excerpt: In this book series on Optical Sciences, holography has been the subject of three previous volumes. In particular, Vol. 16, written by one of us (W. S. ) and Dr. M. Dubas, treated holographic interferometry of opaque bodies from the standpoint of deformation analysis. However, the fundamental principles of holography are developed there only briefly in preparation for a discussion of interference fringe modifications. This new volume in the series is intended to consider in detail many topics which were previously omitted, such as the deformation or distortion of holo graphic images, the theory of volume holograms, composite or multiplex holo graphy, holographic interferometry of transparent media, time dependent effects, holographic contouring, and applications of fringe modifications to the deformation of opaque bodies. In addition, these and other subjects will be treated with the same unifying concept developed in Vol. 16, but with an addi tional emphasis on those features that have their origins in classical optics, espe cially the small-wavelength approach, the coupled-wave theory, and the Seidel aberrations. Since the field of holography and its various applications is growing rapidly, it is impossible to be comprehensive in a single book. Every effort has beep. made to avoid unnecessary duplication of Vol. 16. For example, displace ment and fringe localization problems are only briefly discussed, while some modification techniques (e. g. , sandwich holography) are not included. When needed, however, the reader is directly referred to complementary publications.

This book was released on 1954 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: Laminar, transitional, and turbulent boundary layers were investigated in a subsonic wind tunnel at Mach numbers of 0.55 and 0.78 at various Reynolds numbers and stations along a flat plate. Comparisons are made of the density profiles obtained with a total-pressure probe of smal frontal opening and by means of an x-ray absorption method and, in a few cases, by using interferometer data. The limitations of the probe and x-ray methods are discussed.
