锥形拉瓦尔喷管是超音速分离器能够实现音速分离的关键部件。拉瓦尔喷管的结构尺寸对于气流的加速具有重要作用。通过在给定压力及温度的工况下,改变喷管的喉部尺寸,对锥形拉瓦尔喷管的加速性能进行fluent模拟,得出在相同尺寸参数下,拉瓦尔喷管喉部直径越小,加速性能越优秀的结论。
Conical Laval nozzles are the key components in a supersonic separator capable of sonic separation. The structural dimensions of the Laval nozzle play an important role in accelerating the airflow. By changing the throat size of the nozzle under given pressure and temperature conditions, the fluent simulation of the tapered Laval nozzle accelerating performance is obtained. The results show that under the same size parameters, the Laval nozzle throat diameter Small, accelerating the performance of the more excellent conclusion.
