The influence of combustion efficiency on the characteristics of ramjets

Methods for determining the combustion efficiency, thermodynamics parameters of propellants, and characteristics of ramjets are analyzed. Energetic and multizone models taking into account various physical processes of incomplete combustion are considered. An approach based on comparison of the combustion efficiency evaluated by different models is developed, and recommendations on their application are given. The results and mathematical models presented can be used in numerical computational and experimental studies of the working processes in ramjets.
