Effect of pressure on counterflow H2–air partially premixed flames
A computational investigation of high-pressure hydrogen–air partially premixed flames (PPFs) is reported to characterize the effect of pressure on the flame structure, and the relevance of reaction limits for these flames. The flames are computed using the Mueller mechanism consisting of 19 elementary reactions and 9 species. Although the mechanism has been validated during previous investigati...
متن کاملStructure of partially premixed n-heptane–air counterflow flames
To avoid the complexities associated with the droplet/vapor transport and nonuniform evaporation processes, a fundamental investigation of liquid fuel combustion in idealized configurations is very useful. An experimental–computational investigation of prevaporized n-heptane nonpremixed and partially premixed flames established in a counterflow burner is described. There is a general agreement ...
متن کاملNumerical Investigation of Forced Ignition in Laminar Counterflow Non- Premixed Methane-air Flames
Simulations of forced ignition of non-premixed laminar counterflow flames are used to study the effect of strain rate on ignition success. A one dimensional calculation is performed, using detailed methane chemical kinetics and treating the spark as an instantaneous heat release in an inert mixing layer. Ignition success depends on the mixture composition at the spark location, resulting in lea...
متن کاملDynamics and Suppression Effectiveness of Monodisperse Water Droplets in Non-premixed Counterflow Flames
In situ measurements of velocity and size distributions of initially monodisperse water mists of initial diameters ranging from 14 lm to 42 lm seeded into the air stream of non-premixed propane/air counterflow flames are reported. Droplets were generated piezoelectrically, and the size and velocity distributions and the number density were determined by phase-Doppler particle anemometry. Drople...
