Book excerpt: The Laser Raman Workshop on the r"eas urement of Gas Properti es i sone of aseries of occasional meetings organized in an informal workshop format through the stimulation of Project SQUID, Office of Naval Research. This workshop is the second to be organized on gas-phase applications of Raman scattering. Both Raman workshops were supported by Project SQUID, ONR, and the Air Force Aero Propulsion Laboratory, Wright-Patterson Air Force Base. The first Raman Workshop was held at the AVCO Everett Research Laboratory, Everett, Massachusetts, with their co-sponsorship in January 1972 under the chairmanship of D. A. Leonard. The present meeting was co-sponsored by the General Electric Research and Development Center, and held at their facility in Schenectady, New York. We are grateful to Project SQUID, AFAPL, and GE for their generous financial support of this Workshop, and to Project SQUID for underwriting the publication costs of the Proceedings. As is always the case for successful meetings, many people contributed substantially to the organization and execution of this workshop. Professor Robert Goulard supported, aided, and encouraged us in the most helpful ways, and we are indebted to him. We received further valuable support and assistance from Dr. Ralph Roberts, Director, and Mr. James R. Patton, Jr., of the Power Branch, Office of Naval Research; from Dr. William H. Heiser, Chief Scientist of the Aero Propulsion Laboratory; and from Dr. James M.

Available in PDF, EPUB and Kindle. Book excerpt: The laser Raman scattering technique shows potential as a diagnostic method for determining the chemical and thermodynamic state of high-temperature gases. To investigate the utility of this technique for shock-tube diagnostics, and to validate the method at known elevated temperatures, vibrational Raman intensities were measured behind an incident shock wave. Intensity history data through the wave front, vibrational excitation times of oxygen in air, along with temperature and density measurements for oxygen and nitrogen in air were obtained over a range of postshock conditions. The measured densities and temperatures were found to be in good agreement with shock-wave theory. An excitation time measurement also agreed well with shock-tube data obtained with other diagnostic methods. In general, the results indicated that the Raman scattering technique was accurate at elevated temperatures and should prove useful in determining the thermochemical state of gases in continuous flows as well as in shock tubes and other impulse facilities.

Available in PDF, EPUB and Kindle. Book excerpt: Laser-Raman scattering has been utilized to discover nonequilibrium N2 vibrational levels in a continuous, resistance-heated wind tunnel (Tunnel C) and in an arc-heated wind tunnel (Tunnel F). Vibrational temperatures of up to two times the bulk reservoir temperature have been measured in the Tunnel F free stream. A double-diaphragm device for delay of the Tunnel F nozzle expansion was found to significantly reduce the vibrational temperature level. In tunnel C, the vibrational temperatures were found to be dependent upon the water vapor concentration in the flow. It is hypothesized that water vapor-induced de-excitation of the vibrationally excited nitrogen molecules results in a significant rise in local static temperature and corresponding reduction in Mach number.

This book was released on 2018-07-18 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ultraviolet (UV) spontaneous vibrational Raman scattering combined with laser-induced predissociative fluorescence (LIPF) is developed for temperature and multi-species concentration measurements. Simultaneous measurements of temperature, major species (H2, O2, N2, H2O), and minor species (OH) concentrations are made with a 'single' narrow band KrF excimer laser in subsonic and supersonic lifted turbulent hydrogen-air diffusion flames. The UV Raman system is calibrated with a flat-flame diffusion burner operated at several known equivalence ratios from fuel-lean to fuel-rich. Temperature measurements made by the ratio of Stokes/anti-Stokes signal and by the ideal gas law are compared. The single shot measurement precision for concentration and temperature measurement is 5 to 10 pct. Calibration constants and bandwidth factors are determined from the flat burner measurements and used in a data reduction program to arrive at temperature and species concentration measurements. These simultaneous measurements of temperature and multi-species concentrations allow a better understanding of the complex turbulence-chemistry interactions and provide information for the input and validation of CFD models.

Available in PDF, EPUB and Kindle. Book excerpt: Coherent anti-Stokes spectroscopy (CARS) can be considerably simpler than is suggested by literature analyses based on interactions of monochromatic waves. The simplification arises when the optical properties of real lasers are incorporated into the analysis. To incorporate these properties, it is necessary to recognize that the underlying nonlinear optical interaction has a previously ignored complexity and is dependent on the coherence properties of the fields as well as on their spectra. The coherence of the interaction, as described by the CARS linewidth parameter, is degraded by the imperfect coherence of the laser sources. The occurrence of the nonlinear interaction depends on the small size of laser mode widths, or more fundamentally, on the statistical degeneration of each incident field into a small number of independent fields, a property possessed only by optical fields from lasers. If the lasers' contributions to the linewidth parameter are made dominant, the degree of coherence becomes a fixed property of the apparatus, simplifying interpretation of CARS spectra and extending the range of usefulness of CARS well beyond what would otherwise be expected. Available numerical values plus considerations of effects such as mode frequency chirp suggest that domination of the coherence by the apparatus can be arranged or at least approached in most cases.
