Abstract
In the present work the methane/oxygen combustion process is analyzed in the combustion chamber of a conventional liquid propellant rocket engine (LPRE), using ozone as a process enriching species in order to verify the viability or not of its use in propulsive systems. For this study, simulations were carried out using the ANSYS Fluent 16.2 software package, coupled with a detailed reaction mechanism for the combustion of methane/oxygen/ozone imported from the CHEMKIN software, in order to capture its effect on combustion and bring the results as close to reality as possible. Through this work, was possible to verify that ozone has indeed enriching potential in the combustion of methane/oxygen, generating increases of about 100K in the temperature of the chamber, which can lead to lower fuel consumption.
