The proposed effort can provide the framework for a unified modeling & simulation program to substantially improve the capability for understanding, analyzing, and predicting the underlying mechanisms dictating the combustion stability characteristics of liquid-propellant rocket engines. Emphasis will be placed on the effects of atomization, mixing, and distributed combustion of liquid oxygen (LOX) and kerosene propellants under conditions representative of oxygen-rich preburner staged-combustion cycle (ORPSC) engines. New models and solution methodologies will be developed and validated, where necessary, to further enhance the solution accuracy and efficiency. The Phase I effort will focus on the flow evolution and flame dynamics of single element coaxial swirl injectors typical of the preburner and main chamber applications with liquid/liquid and gas/liquid mixtures, respectively.
