In the work general parameters of ejector similarities are derived power-supply factor, momentum factor and pressure drop. These parameters make it possible to calculate and experimentally determine the general characteristics of ejectors which are then appropriate for a physically clear and simple determination of an optimum ejector for any application, depending on given boundary conditions. A simulation theory has been expanded to the required recommendations for designing ejectors. Author
