Processes in an Oxygen–Methane Combustion Chamber with Gaseous Fuel

The processes in an oxygen–methane combustion chamber with gaseous fuel are studied by three-dimensional numerical modeling. The advantages and disadvantages of the modeling method based on the gross reaction equation for the stoichiometric composition are considered. Eddy dissipation is considered as the model of combustion. The working fluid is assumed to be an ideal gas. The behavior in the combustion chamber according to modeling is analyzed. The results of three-dimensional modeling and thermodynamic analysis are compared. Recommendations are made for improving the design and efficiency of the combustion chamber.
