タイトル（掲載誌）航空宇宙技術研究所報告 = Technical Report of National Aerospace Laboratory TR-769
一般注記An analytical computing model for performing LO2/LH2 rocket combustor performance analysis was derived by using the results of former studies of spray flow field characteristics of Liquid/Gas coaxial injector elements. The each process of liquid atomization, mixing of liquid phase to gas phase and vaporization of liquid droplets are the combustion controlling model. In formulating the analytical combustion model, the combustion zone was subdivided into a series of two discrete zones along the axis of the combustion chamber. At the region immediately adjacent to the propellant injector, the flow is characterized by the behavior of the spray jet from the injector elements. And after each spray jet interactes with each other, the flow is assumed almost one dimensional expect for the mass flux distribution of liquid droplets. For the first region, spray flow field characteristics which were obtained in former studies by the author were applied in modifing the confined spray jet characteristics. By this analytical model, the calculation of combustion gas parameters and liquid droplets histories along the chamber axis, the prediction of C efficiencies and the calculation of heat flux distribution were performed for sub-scaled combustors and actual rocket engines such as the RL-10, LE-5 and HM-7. The predicted C efficiencies were almost within ±2％, compared to the values obtained from experiments. The calculated heat flux values were also in close agreement with values obtained from experiments.
