The fluid flows in the core, from the injector and in the nozzle and plume of the rocket, are high-temperature, high-speed, highly turbulent flows, with entrained chemically reacting aluminum particles from the propellant. To predict unsteady pressure conditions in the combustion region, the aeroacoustic forcing of acoustic instabilities, heat and mass transfer to the propellant and nozzle, and erosion of the nozzle by the particles, a three-dimensional, time-dependent simulation of the large scales of turbulent motion is needed. In addition, the fluid simulation must account for mass and heat injection from the propellant, the roughness of the interface, and compressibility and shocks in the nozzle and plume. There are three interrelated issues to be addressed in performing the turbulent fluid flow simulations: (1) formulation and modeling of the equations governing the large scales of turbulence, (2) treatment of the particles in the flow and (3) numerical representation,...
