Adding flamelet/progress variable approach to computation platform developed by ourselves

two kinds of progress variable were adopted to simulate methane/air coaxial jet combustor. Comparing the results with each other and also with steady flamelet model

literature reference and experiment result

it is indicated that the results of flamelet/progress variable approaches can compute unsteady phenomenon in combustion

such as lifted flame which can not be observed in steady flamelet model

and agree reasonably well with the literature reference and experiment result

namely

they can reflect the actual process of combustion accurately; at the same time it is learnt that different definitions of progress variables lead to different results; it is proved that flamelet/progress variable approaches do better in simulating main auxiliary production carbon monoxide

and are closer to experiment result.
