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.

In this paper, the Mach number control system in NF-6 wind tunnel is introduced, especially in detail for the compressor rotary speed control sub-system, the compressor stator vane control sub-system and the second throat control sub-system.
