摘要: Abstract Laminar burning velocities of ethanol-water-air mixtures have been determined using the heat flux method. Aqueous ethanol contained 0–40% water by mole fraction. premixed flat flames were stabilized on a perforated burner under adiabatic conditions for equivalence ratio range from 0.7 to 1.4. Burning velocity measurements performed initial gas temperature 358 K and at atmospheric pressure. The results ethanol-air are in good agreement with previous data obtained same present literature experimental compared against predictions four different kinetic models. All models show uniform behaviour over dilution covered study. However, model significantly diverge spherical flames. To quantify effect laminar velocity, an empirical dimensionless correlation has derived tested. Further numerical analyses identify effects addition velocities. Results suggested that strongly interacts H2/O2 C1 oxidation/recombination routes.
