Abstract:

his paper describes the structure and functions of a modeling codefor the combustion and flow in liquid rocket engine(CAFILRE). CAFILRE is a general two-dimensional numerical model which has been developed with modularstructure. It is capable of modeling the complex processes of atomization, evaporization, turbulent mixing and combustion in combustion chambers of liquid propellant rocket engines. Therefore, the code can be used to predict the performance of rocketengines and to optimize the design parameters.
