Supersonic Combustion of Kerosene/H₂-Mixtures in a Model Scramjet Combustor

Rapid quenching by supersonic expansion and injection of water

“…In these combustion systems atomization and mixing with the air are of prime importance to reduce pollutant emissions and increase combustion efficiency. A general overview on supersonic combustion is given by Billig (1993), whereas investigations on supersonic combustion of traverse injected kerosene jets are presented by Gruenig and Mayinger (1999) and Yu et al (2002). There are various publications on crossflow injection.…”

Numerical simulations of single and multi-staged injection of H2 in a supersonic scramjet combustor

“…This is the result of hydrogen's properties such as high heat of combustion (141.9 kJ/g), high molecular diffusion velocity, and high specific heat, i.e., its cooling capacity. In fact, the cooling capacity is one of the most important properties that strongly influence the fuel selection for high speed flight systems [20].…”

Mathematical Modeling and Analysis of Different Type of Fuel Injector in Scramjet Engine Using CFD Simulation in Fluent

“…The oblique detonation wave angle may not be controlled by the wedge angle under weak under driven solution conditions and be determined only by combustion velocity. Gruenig and F. Mayinger [5] worked on the topic of "Supersonic combustion of kerosene/h2-mixtures in a model Scramjet combustor", and their findings are -The necessary temperature level is partly achieved by the oblique shock waves in the supersonic flow with increasing combustor area ratio. K. Kumaran and V. Babu [6] worked on the topic of "Investigation of the effect of chemistry models on the numerical predictions of the supersonic combustion of hydrogen", and their findings are -Multi step chemistry predicts higher and wider spread heat release than what is predicted by single step chemistry.…”
