In this book the theoretical and experimental analysis of optimal geometry and cavitational flow characteristics of the ejector were done. The analysis of fluid flow in the ejector for incompressible fluid were determined, the parameters of optimal efficiency values of the ejectors. A method for analyzing the ejector, defined by cavitational mode of jets and chamber ejectors and operation of the ejector in heating substation. The theoretical results obtained were verified by experiment.
