Computational analysis on internal performance of a convergent-divergent nozzle with throat fluidic injection
The results of a computational study were presented to investigate the impact of throat fluidic injection on the flow field in an axisymmetric nozzle.With the increase of secondary pressure ratio(SPR)
both the nozzle thrust ratio and mass flow ratio were reduced under the same nozzle pressure ratio(NPR).In addition
the effect of throat fluidic injection on the nozzle thrust ratio was less than 2%
but the effect on the nozzle mass flow ratio more than 15%.With the impact of the divergence ratio and adjustment sheet of the nozzle on the throat control effect presented
a better nozzle model was obtained within the scope of the investigation.
