    The Impact of Some Factors of Thermal Protection Material Degradation on the Discharge Coefficient of the Recessed Nozzle

    The Impact of Some Factors of Thermal Protection Material Degradation on the Discharge Coefficient of the Recessed Nozzle


    Computational fluid dynamics was employed to study the effect of temperature and composition of injected thermal protection degradation products on the discharge coefficient of the recessed nozzle. The analysis was carried out together with simulation of blowing intensity of degradation products into the main flow with variation of the heat flux along the nozzle entrance. The behavior of flow parameters over the nozzle entrance region and variation of the discharge coefficient depending on the parameters of injected gas were described.
