The paper presents the development and implementation of a Large Eddy Simulation numerical algorithm for simulating turbulent reactive flows. The numerical algorithm is based on a 5 step modified Runge - Kutta numerical scheme with a dual time stepping numerical convergence acceleration technique, and employs a Localized Dynamic Turbulent Kinetic Energy turbulence model. The chemical reaction part of the algorithm is handled by a Linear Eddy Mixing combustion model. The paper described in brief the numerical algorithm, the turbulence model and the combustion model, highlighting the improvements they bring to the numerical solution in terms of accuracy and suitability to real life combustion problems. The algorithm validation is also performed, by comparison to experimental data and the literature and the superior algorithm accuracy is highlighted by comparison to numerical data resulting from previous numerical studies. The algorithm presented here is, to the knowledge of the authors, the first such complex implementation on Romania and will be used by Romanian researchers to tackle complex turbulent combustion problems with state-of-the-art methods and computational tools.
