MS2-3 Conditional Moment Closure with a Progress Variable Approach (MS: Modeling and Simulation, General Session Papers)

A method has been developed that allows for performing reactive flow simulations using conditional moment closure (CMC) without spatial dimension reduction of the CMC grid. The CMC is performed for a progress variable and the emission scalars, using a progress variable parameterization of the combustion chemistry. The method has been implemented into a CFD software package. The proposed method has been tested for a simple spray bomb case, n-heptane spray injection into a constant volume vessel, and compared with the interactive flamelet model.
