Multiple Mapping Conditioning Mixing Time Scales for Turbulent Premixed Flames

Abstract A novel multiple mapping conditioning (MMC) mixing time scale model for turbulent premixed combustion has been developed. It combines scales the flamelet and distributed flame regimes with aid of a blending function. The function serves two purposes. Firstly, it helps to identify zones where resides associated shall be used. Secondly, uses Karlovitz number regime reduce weighting if numbers are high deviations from expected. series three-dimensional direct numerical simulations (DNS) statistically one dimensional, freely propagating methane-air flames provides wide range validation. new correct predictions speed which could not matched by most recognized models. structure predicted is in good agreement DNS all thickened reaction zone.
