<h1>A Consistent MMC-LES Approach for Turbulent Premixed Flames</h1>

This data set contains case setups to reproduce the simulation results presented in Iaroslavtceva et al. (2024) Proceedings of the Combustion Institute. In this publication, a set of freely propagating turbulent premixed flames with varying equivalence ratios is used to test the performance of Multiple Mapping Conditioning (MMC) model. MMC coupled with Large Eddy Simulation (LES) provides a closure
of the filtered chemical source term. Results of MMC-LES are compared with reference Direct Numerical Simulations (DNS) that include full chemistry. Additional simulations were carried out where MMC is coupled with quasi-DNS where the flow field is fully resolved but the reaction progress variable field is thickened and its source term is closed with a flamelet approach. This allows to isolate the different modelling assumptions invoked in MMC-LES.

<h1>Data structure</h1>

The setups for the following cases are presented:
<ul>
<li> Equivalence ratio = 0.6 (MMC-quasi-DNS): eqRatio0_6/MMC-DNS</li>
<li> Equivalence ratio = 0.6 (MMC-ATF-DNS): eqRatio0_6/MMC-ATF-DNS </li>
<li> Equivalence ratio = 0.6 (MMC-LES): eqRatio0_6/MMC-LES </li>
<li> Equivalence ratio = 0.6 (DNS): eqRatio0_6/DNS </li>
<li> Equivalence ratio = 1.0 (MMC-LES): eqRatio1/MMC-LES </li>
<li> Equivalence ratio = 1.0 (DNS): eqRatio1/DNS </li>
<li> Equivalence ratio = 0.25 (MMC-LES): eqRatio0_25/MMC-LES </li>
<li> Equivalence ratio = 0.25 (DNS): eqRatio0_25/DNS </li>
</ul>

Instructions on how to run the cases can be found in each case folder in README file.
