A newly developed two-dimensionalaxisymmetric program for the simulation of three-phase reactive flows is presented. The three phases are a multiple-species gaseous phase, a single-species liquid phase, and a particulate droplet phase. The liquid and gaseous phases are described with continuous Eulerian equations, while the droplets are described in a discrete Lagrangian fashion. The three phases are fully coupled together. An atomization model, a multireaction chemical kinetics model, and a subgrid scale turbulence model completes the description of a general liquidgas bipropellant combustion process. This paper will emphasize on highlighting the code development criteria and qualitative features rather than the complete mathematical details, which will be presented in a later report.
