abstract

In this paper is described a computational fluid dynamic (CFD ) modeling tool based on the Multi-Environment Probability Density Function (MEPDF) method developed specifically to account for finite rate chemistry effects in modeling practical combustion systems. MEPDF originated from multi-environment micro-mixing models used in the chemical engineering community to simulate chemical processes with little or no heat release. Previous uses of MEPDF for combustion applications typically used simple chemistry models. Our work has focused on extending the MEPDF method for combustion applications using detailed chemistry models. Provided below is an overview of the MEPDF formulation and example calculations. The model has been shown to use substantially less computational time compared to more traditional PDF methods using a Monte-Carlo approach.
