Abstract
A numerical study on the asymmetric nozzle with a moving plate was conducted. The thrust vector control of the nozzle was investigated based on the transient phenomenon of a supersonic jet. The primary stream was exhausted from a convergent-divergent nozzle and deflected by the upper nozzle wall, which slid forward and backward according to certain motions. The transient flow behavior was numerically accessed by the unsteady Reynolds averaged Navier-Stokes equations coupled with a Reynolds stress turbulence model using a fully implicit finite volume scheme. Results of the primary numerical analysis were in good agreement with existing experimental data. The time-dependent system characteristics were specified in terms of vector angle, system thrust ratio and thrust loss.
