Research output: Contribution to journalArticlepeer-review


Calculations have been made of the three-dimensional mixing, chemical reaction, and flowfieid development in a typical ducted rocket configuration. The governing partial differentia) equations are numerically solved by an iterative finite-difference solution procedure. The physical models include the ke turbulence model, onestep reaction, and mixing controlled chemical reaction rate. Radiation is neglected. The mean flow structure, fuel dispersal patterns, and temperature field are presented in detail for a base configuration with a 0.058 m dome height, 45-deg side-arm inclination, and with gaseous ethylene injected from the dome plate at an eccentric location. In addition, the influences of the geometrical parameters, such as dome height, inclination of the side arms, and location of the fuel injector, are studied.
