O autorze

Dr. Giuseppe Grazzini is Professor of Thermodynamics and Heat Transfer at the University of Florence. He has been active in research on ejectors for over two decades. He led the Thermodynamics and Heat Transfer Laboratory research group at Florence University, supervising the development of the first prototype of an ejector chiller. He has published his results widely in international scientific journals.

Dr. Adriano Milazzo is Associate Professor of Thermodynamics and Heat Transfer at the University of Florence. He has published multiple papers in international scientific journals on ejectors, and coordinated the design of the ejector chiller prototype at Frigel Firenze, a leader in advanced process cooling technology.

Dr. Federico Mazzelli is Lecturer of Thermodynamics and Heat Transfer at the University of Florence. He earned his Ph.D. at University of Florence working on the experimental and numerical analysis of an industrial ejector chiller. His current research focuses on the CFD analysis of multiphase supersonic ejectors.

Blurb

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.
