要約

Three various approaches to calculation of the laminar (normal) burning velocity SL (un) of fuel mixtures of different compositions based on two-parametric semiempiric generalization (TPG) and upon a chemical kinetics mechanism have been developed and verified. The first technique (TPG 1) is related to un definition for mixtures of low-calorific gases and their mixtures with methane as well as to hydrocarbon combustion velocities. The second method (TPG 2) uses the correction factor, for taking into account the preheating mixture temperature and initial pressure (introducing the two simplexes in form of a power law: (Tin/T0)n (Pin/P0)γ. Oxidants used were air and oxygen-enriched air, both of dry and humidified composition. By our approach an application of GRI-Mech 3.0 combustion mechanism has been modernized and improved proven to make the most universal procedure. Validation of our computed data by a set of predicted un has been performed regarding measured values and appropriate literature sources.
