Barata Computational study on coaxial nitrogen-hydrogen injection at supercritical conditions AIAA SciTech 2022 Forum and Exposition, Evento Hibrido, San Diego, CA, EUA, 3-7 janeiro, 2022978-162410631-6http://hdl.handle.net/10400.6/12154In the present work, we perform a computational study on the mixing of nitrogen and hydrogen at supercritical conditions. A coaxial injection configuration is considered where nitrogen is injected through the central post with a hydrogen co-flow. The flow in both injectors as well as in the combustion chamber is considered in the computations. This preliminary version presents the radial density profiles maximum of both species and radial density profiles at selected locations.engCombustion ChambersHeat TransferViscosityGas ConstantThermal ConductivityPropellantConservation EquationsThermodynamic PropertiesRocket Thrust ChamberFinite Volume Methodjournal article10.2514/6.2022-0877
