Book Description
An optical diagnostic system for turbulent shear flows was developed based on a Shack-Hartmann wavefront sensor. The sensor uses discrete lenslets to image small portions of the flow to determine the wavefront distortion caused by turbulent interfaces. The technique is particularly useful to identify turbulent coherent structure. The system was demonstrated for a plane mixing layer with small heat addition causing temperature to act as the passive scalar.

Book Description
Over the past several years, the Principal Investigator has made significant contributions to the to the understanding of compressible turbulent flows. He has utilized innovative modern optical diagnostics to explore (1) the turbulence structure of wall bounded shear layers, (2) the effects of extra strain rates, such as convex curvature and favorable pressure gradient, on the turbulence structure of wall bounded shear layers, (3) the effect of compressibility on the Reynolds stresses and the turbulence structure of free shear layers, and (4) control of supersonic jets. The latest state-of-the-art optical diagnostics that the PI has been using include Filtered Rayleigh Scattering (FRS) technique for flow visualizations, and Planar Doppler Velocimetry (PDV) technique for 4-instantaneous velocity measurements.

Book Description
The origin of optical methods for fluid flow investigations appears to be nontraceable. This is no matter for surprise. After all seeing provides the most direct and common way for humans to learn about their environment. But at the same time some of the most sophisticated methods for doing measurements in fluids are also based on light and often laser light. A very large amount of material has been published in this area over the last two decades. Why then another publication? Well, the field is still in a state of rapid development. It is characterised by the use of results and methods developed within very different areas like optical physics, spectroscopy, communication systems, electronics and computer science, mechanical engineering, chemical engineering and, of course, fluid dynamics. We are not aware of a book containing both introductory and more advanced material that covers the same material as presented here. The book is the result of a compilation and expansion of material presented at a summer school on Optical Diagnosticsfor Flow Processes,held at RiS0 National Laboratory and the Technical University of Denmark in September 1993. The aim of the course was to provide a solid background for understanding, evaluating, and using modem optical diagnostic methods, addressing Ph. D. students and researchers active in areas of fluid flow research. The disciplines represented by the participants ranged from atmospheric fluid dynamics to biomedicine.
