air uptake

In order to study the influence of the ratios of injection pressure and injection temperature,injection slot width and jet angle on fluidic throat control,a two-dimensional flow field inside a nozzle and around it with a jet flow at the throat is numerically simulated by computing the N-S equation through second-order wind disperse schemes and an S-A model.

采用二阶迎风格式,并结合S-A湍流模型求解N-S方程,对喉部注气的二元拉瓦尔喷管内部和周围流场进行了二维数值模拟,分析了注气总压比、注气总温比、射流缝缝宽和注气角度对喷管气动喉道控制的影响。
