Abstract
In this paper, we combine the Eulerian stochastic field (ESF) model with flamelet generated manifolds (FGM) model to achieve a new type of turbulent combustion flamelet model with high accuracy under consideration of the detailed chemical reaction mechanism. It solves the limitations of using the presumed PDF model in the original FGM model and the problems of the FGM model in the promotion of the use of non-applicability and other issues. Using OpenFOAM software and Sandia Flame D experimental data to complete the model to achieve and verify. The results show: the simulation results of the new model are good, which can accurately simulate the axial and radial temperature and the distribution of the mass fraction of the main components, and the accuracy is better than the original FGM model; with the increase of the number of stochastic fields in the ESF model, the accuracy of simulation is continuously improved; when the number of stochastic fields increases to a certain value, the simulation results are stable within a certain range of variation. The above results show that the model is effective for this type of flame simulation and has good prospects for simulating a more complex flame.
