Abstract

In this study a new method for computing reacting flow in POROUS MEDIA is presented, which can be considered as a combination of two existing reduced chemistry approaches, i.e. the flamelet and manifold approach, to speed up flame calculations. This method, referred to as the Flamelet- Generated Manifold (FGM), shares the idea with the flamelet approaches that a multi-dimensional flame may be considered as a set of one- dimensional flames. The thermo- chemical variables are stored in a database, which can be used in subsequent flame simulations. During flame simulation, conservation equations have to be solved for the controlling variables only. Test results of a two-dimensional methane/ air flame shows that detailed chemistry computations are reproduced very well using FGM with only one progress variable, apart from the enthalpy to account for energy losses. Using the FGM METHOD, the computation time has been reduced several times that demonstrates the enormous potential of this method. In addition, submerged flames within a porous medium are simulated to show the applicability of the presented method in predicting reacting flow in variable enthalpy problems. The predicted solid and gas temperatures are comparable with experimental values that demonstrates the ability of the FGM METHOD.
