説明

Author analysed the problems of injector and ejector, which consist of low pressure jet and mixing part, in wide range. Especially, the efficiency in mixing part of this apparatus, which is straight part or tube, was discussed, and the theoretical efficieney in mixing part showed very simple curve in ηth-β (ηth is theoretical efficiency in mixing part, and β is {1+(M-1)γj/γs}/B. Where M is mass ratio, B is area ratio, γj is the weight of the jet fluid per unit volume in jet fluid, and γs is the weight of the sucked-in fluid per unit volume. Then author discussed combined jet apparatuses which consist of many jets or mixing part, and explained their efficiency.
