主控制室核级空气喷射器性能影响因素研究
Factors influencing performance of nuclear air ejector in main control rooms
摘要：
空气喷射器在非能动压水堆核电站发生事故时用于主控制室的应急通风。建立试验系统对空气喷射器的性能进行了研究，基于试验系统建立了模型，分析了空气喷射器的性能。认为压缩空气入口流量是影响空气喷射器喷射系数和出口空气压力的重要参数；喷嘴与混合腔的距离、喷嘴直径及混合腔截面与喷嘴出口面积之比是影响喷射系数和出口空气压力的重要因素。
Abstract：
An air ejector is used for emergency ventilation of the main control room when an accident happens in a pressurized water reactor nuclear power station. Sets up a system to test the performance of ejector. Based on the test system, establishes a model and analyses the performance of the air ejector. The results indicate that the inlet flow rate of compressed air is an important factor impacting the jet coefficient and the outlet air pressure of the air ejector. The distance between nozzle and mix section, the nozzle diameter and the area ratio between mix section and nozzle outlet are the important impact factors of the jet coefficient and outlet air pressure.
