Abstract

The flow in the nozzle of a solid propellant rocket is characterized by a two-phase flow including A1₂O₃ particles generated by combustion. The present study was conducted for the numerical analysis on the particle laden flow around a jet vane device which is installed at the end of the nozzle for the thrust vector control. The particle accretion rate on the vane surface was obtained as the fundamental information of the vane erosion analysis. Primarily, the analysis of the flow was carried out around a simple two dimensional jet vane model and then an actual three dimensional jet vane to understand the two phase flow phenomena. The vane turning angle and the particle size were considered as the main parameters changed from 0° to 20° and from 0.5μm to 20μm, respectively.
