Numerical Simulation of Sandia D Flame Using Optimized k-e Transport Model-Based Eddy Dissipation Concept

EasyChair Preprint 11146

Abstract

The aim of this study was to develop an efficient computational tool for transient reacting flows, specifically focusing on stationary flames. The tool was based on the Reynolds-averaged Navier-Stokes (RANS) equations and employed the k-ε turbulence model. The validation process involved using various single-step chemical kinetics models to simulate methane combustion in a Sandia D flame case. This simulation was carried out using the Eddy Dissipation Concept (EDC) within the OpenFOAM open-source Computational Fluid Dynamics (CFD) code. The findings from the validation revealed that the EDC model was the most effective choice for this application. Following this, the researchers applied several corrections to the k-ε model to further optimize the EDC model. Among these corrections, Pope's correction proved to be the most successful. Subsequent investigations delved into the variations within the EDC combustion model. After analyzing different versions, the EDC 81 model emerged as the most suitable for achieving accurate predictions as compared to any of the existing EDC models as proposed till date.
