| Summary: | In this research, the effects of some liquid side injection from nozzle wall into exhaust gas of combustion
chamber are studied. The side injection against main flow is as elliptical solid thing that change the
symmetric of flow field on nozzle wall and causes some different pressure distribution on wall, and finally
causes thrust vector deviation. Flows interaction causes some physical phenomena as bow shock wave in
front of injection region. This paper explain the effects of this wave and variation velocity & pressure
distribution at different cross sections of flow field and comparison results of air and other liquid fluid in
thrust vector control system. The results are compared with experimental data and have well agreement with
them. The results show that Freon is one of best injection liquid for this type of thrust vector control.
Performance of Injection is optimum in relative position 35 to 40% nozzle divergence length. |
