Soret and Dilution Effects on Premixed Flames

摘要: Abstract The structure of a wrinkled premixed flame is analysed theoretically. By assuming the reactive mixture diluted in an inert gas and weak cross-diffusion coupling between heat mass fluxes, effect change by reaction physical properties (thermal conductivity, specific heat, number molecules) Soret Dufour diffusions have been investigated limit high activation energies. It turns out that diffusion cannot be neglected study front dynamics. In contrast, as well generally appears to play minor role.
