Encompassing both practical applications and recent research developments, this book takes the reader from fundamental physics, through cutting-edge new designs of ejectors for refrigeration. The authors’ unique vision marries successful design, system optimization, and operation experience with insights on the application of cutting-edge Computational Fluid Dynamics (CFD) models. This robust treatment leads the way forward in developing improved ejector technologies. The book covers ejectors used for heat powered refrigeration and for expansion work recovery in compression refrigerators, with special emphasis on two-phase flows of “natural” fluids within the ejector, i.e. steam and carbon dioxide. It features worked examples, detailed research results, and analysis tools.

The turbulent mixing region of a two-dimensional, supersonic, air-air ejector system was experimentally investigated utilizing an interferometer. Density distributions for the two-stream mixing region within the ejector duct were established for 6 different test configurations. Similarity of the density distributions was indicated for mixing region cross sections as close as one nozzleexit hydraulic diameter from the nozzle. Density profiles at successive downstream duct locations were plotted to show the spread of the mixing region. The effect of normal and oblique shocks on the rate of spread of the mixing region was found to be small. In addition, ejector performance data and techniques for spark lamp photography are presented. It is concluded that the interferometer could be effectively utilized to help determine the transport coefficients of ejector system turbulent mixing processes. (Author).
