| Abstract | A numerical study was conducted to investigate the effects of secondary gaseous injection into primary supersonic gas stream by characterizing the resulting flowfield and estimating the thrust vector control performance for a 2DCD nozzle. Flowfield structure and performance parameters were systematically investigated for several variables such as secondary (injectant) stagnation pressure, injection slot area, angle of injection, and primary nozzle profile. FLUENT, a commercial CFD software was employed for current numerical investigation. 2D coupled-implicit solver with realizable k-epsilon viscous model was used throughout the research. The results showed that flowfield structure and performance parameters were primarily influenced by injectant mass flow rate, injection location, and primary nozzle profile whereas injection angle was less influential for the range of parameters investigated. An important aspect of the research was the identification of the safe injection limits for a specific configuration. Numerical estimations were found to have fairly close agreement with analytical results. |
