副喷管 meaning in English

secondary nozzle

The discussing emphases are structural and stagnation parameters of ejecting nozzles and secondary fuel nozzles
重点对喉部引射主喷管和燃料副喷管的不同结构、滞止参数进行探讨。
Characteristic of flow - fields at throat of oxidant nozzle , way to separate the equivalent three - nozzle , ejecting effect of different parameters and engineering situations have been demonstrated . effect of distance between secondary flows , the jet angle and the total pressure on the status of flow - fields , has been studied . reactive flow in a hyten nozzle with dimension that was primarily determined has been simulated
研究了喉部引射主喷管的流场特征、主喷管等效的三喷管分离方法和不同参数的引射结果以及相关的工程问题；同时还研究了hyten的流场特征，不同副喷管间距、注入角度和总压对流场参数的影响。
