Pages : 424
Book Description
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.

Shock-tube Diagnostics Utilizing Laser Raman Spectroscopy
Author: Anthony A. Boiarski

ISBN:
Category : Gas dynamics
Languages : en
Pages : 100
Book Description
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.

Appicability of Laser Raman Scattering Diagnostic Techniques to Practical Combustion Systems
Author: Alan C. Eckbreth
Publisher:
ISBN:
Category :
Languages : en
Pages : 97
Book Description
Laser Raman scattering techniques for combustion diagnosis have undergone considerable development in the past several years and are now being employed in a number of fundamental flame investigations. However, from an instrumentation viewpoint, practical combustion environments can differ greatly from the flames typically employed in fundamental studies. In particular, pulsed laser Raman thermometry experiments have shown laser modulated particulate (soot) incandescence to be an especially severe problem. Particles in the measurement volume, which, at flame temperatures, are already incandescent and contribute significantly to the total luminous emission, absorb the incident Raman inducing laser radiation, heat to temperatures far above ambient, and emit greatly increased amounts of gray/blackbody radiation which can exceed the sought-for Raman signal levels by several orders of magnitude. Under Project SQUID sponsorship, a detailed study of this phenomenon has been conducted, the results of which are reported herein.
