Abstract

We consider a 2-dimensional model of a turbulent, methane flame. The model is based on the compressible Navier-Stokes equations extended with a temperature equation and chemical reaction properties. In order to achieve a high-quality real-time simulation, a fully adaptive finite element method is used to solve the considered system of equations. The method performs adaptive mesh refinement, local adjustment of the approximation order, and multilevel adaptation. The structure and composition of the flame, along with the numerical properties of the method, such as the mesh density, are studied. The results are compared to results obtained with a direct numerical simulation.
