| 摘 要： | 缩扩型的拉瓦尔喷管可以使通过其的气流获得超音速,出口速度的大小以及气流是否稳定是决定拉瓦尔喷管性能优劣的关键因素.通过Fluent软件对拉瓦尔喷管的相关流场进行了数值仿真,分析了入口压力、面积比、收缩段型面及扩张段的锥角对喷管出流速度的影响,可为喷嘴的设计提供理论指导.

| Abstract: | Owing that the supersonic airflow is generated through the scaling Laval nozzles,the outlet velocity and airflow stability are critical to nozzle performances.Based on the numerical simulation on relevant flow fields using Fluent software,such impacts as inlet pressure,area ratio,the contracting section and expanding cone-angle upon outlet velocity are analyzed to set a theoretical reference to nozzle design. |
