Laminar flame propagation in supercritical hydrogen/air and methane/air mixtures

The propagation of laminar hydrogen/air and methane/air flames in supercritical conditions was computationally simulated for the planar flame configurations, incorporating descriptions of supercritical thermodynamics and transport as well as high-pressure chemical kinetics. The inaccuracies associated with the use of ideal gas assumptions for various components of the supercritical description were systematically assessed with progressively more...
