Design and experiment of constant-pressure mixing ejector

A simple engineering method is developed to design and predict the performance of the constant-mixing ejector. The influence of ejector parameters on performance is also analyzed. Since the method is formulated in terms of enthalpy, it is applicable to all kinds of primary and secondary gases. In order to control ejector size, the multi-nozzle type and the constant-mixing ejector are integrated. For purpose of verification, the method is compared with experiment results.
