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。
