【Abstract】 The operating process of multi nozzle ejector is analyzed,a theoratical model is presented for calculating the performance data of multiple nozzle ejector with a constant area mixing tube,factors influencing on the ejector performance data are also determined.Experiments have been done to verify this theoratical calculating model,and results indicate that experimental data are comparable to theoratically calculated data within the range of operating conditions described.This calculating model may be used for reference as the multi nozzle ejector system is designed.更多还原
