Abstract

H2O2/kerosene bipropellants are effective alternatives for toxic propellants currently in use. The complex H2O2/kerosene turbulent flow and combustion chemical reaction are modeled, the atomization, evaporation and mixing are investigated, the characteristics of the complex chemical reaction path of kerosene at different stages in combustion chamber are analyzed, and the profiles of static pressure, temperature and Mach number of exhaust plume are provided. During the kerosene injection, the spray angle is 13 degrees, the atomization and evaporation occur and complete simultaneously, the lasting time of atomization is about 1 ms, and the maximal vaporization rate reaches 1.5 x 10(-6) kg/s. The combustion chamber can be divided into the following three zones: rapid high-temperature pyrolysis zone, oxidization zone and equilibrium flow zone. The initial excitation of kerosene reactions is crucial link, and the hydrogen abstraction reactions are the dominant reactions in the high pyrolysis. These peak values of static pressure, temperature, Mach number along plume axis almost evenly distribute, and the interval distances are about 32 mm along the centerline of axis.
