Design and experiment of constant-pressure mixing ejector
-
摘要: 采用1维处理方法，建立了便于设计人员使用的等压混合引射器性能计算分析与工程设计方法，并详细分析了等压混合引射器各主要参数对性能的影响。该分析方法基于气体焓的变化，因此可应用于各种引射气体与被引射气体。为了控制尺寸，还首次将多喷嘴引射方式与等压混合结合起来。实验结果验证了等压混合引射器性能计算分析与工程设计方法的可靠性以及多喷嘴引射方式应用于等压混合引射器的可行性。Abstract: 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.
