Abstract:

In recent years many optical measuring methods, most using lasers, for determining flow velocity with turbulence and fluctuations, temperature and species concentration have been studied. The main advantage is that the flow is not disturbed. They are of great value for research and development on engines and components and for the understanding of fundamental flow processes. The proposed lecture series will inform propulsion specialists of the techniques that are currently available, how to use them and their limitations. It will review experience to date in practical applications. Laser-velocimetry will be emphasized since it is the only technique which has achieved practical importance up until now. Raman scattering and holography interferometry will also be addressed. Commonly-used techniques and qualitative type methods such as infrared for surface temperature and Schlieren techniques will not be addressed. A bibliography of 98 items is included in the publication. Author
