Comparison of ramjet and scramjet modes in the combustion chamber of the HIFIRE-2 experiment

This paper describes a three-dimensional model for calculating a propulsion system run-ning on hydrocarbon fuel. A global kinetic mechanism of the combustion of JP-7 avia-tion kerosene is presented. The study of the structure of the flow in the HiFire-2 engine was carried out, and the fields of concentrations and temperature were obtained. A quali-tative comparison of the results obtained with the calculations of other authors has been carried out. The difference in the operating modes of the ramjet and scramjet is shown.
