The unity Lewis (Le) number assumption has been studied in 2D DNS of atmospheric pressure Kerosene/Air flames for both a real gas (RGL) and the ideal gas law (IGL) equation of states (EOS) models. The comparison of non-unity and unity Le number atmospheric pressure flames has been done since it has a crucial importance to help to better understand the influence of the unity Le number assumption on these flames. In order to verify the acceptability of the unity Le assumption in hydrocarbon flames, similar trends in flame structures should be obtained.
