Abstract
This paper investigates the high-density combustion in a GOX/kerosene combustion chamber using Large Eddy Simulations. Since the prevailing conditions are such that the ideal gas equation of state cannot be justifiably employed, a real gas equation of state is needed in conjunction with an appropriate mixing rule to establish the averaged state properties of the mixture. The chemical kinetics is incorporated in the simulations through the steady laminar flamelet. The flamelet model is based on a global reaction of n-dodecane. A new approach is also used to determine the parameters of a cubic equation of state from the transport data of the chemical kinetic model. The difference in the flow field resulting from the use of real gas model is established by comparing with simulations in idea gas model is used. The difference justified the use of the real gas model.
