On Numerical Simulation of Flows in Scramjet Combustor Using OpenFOAM

The methodology and the results of numerical simulation of flows in the scramjet combustor using the open source CFD-toolbox OpenFOAM are provided. The combustor chamber is supplied with gas phase hydrocarbon fuel. The dynamics of combustion processes is studied depending on oxidizer-to-fuel ratio. The system of the Reynolds-averaged Navier-Stokes equations with additional terms and equations taking into account the effects of turbulence and combustion is used as a mathematical model.
