Kurzbeschreibung (Abstract)
A steady CFD-Flamelet/Progress variable model is implemented for the simulation of a gasifier. In this model, the open source code OpenFOAM is used to solve the partial differential equations of mass, momentum, turbulence, fuel mixture fraction mean of fuel and its variance, mean mixture fraction of steam and the progress variable, respectively. On the other hand, the species mass fractions are retrieved from a precomputed flamelet look-up table. Finally, the simulations results obtained with the steady CFD-Flamelet/Progress Variable (FPV) are compared with the available pilot plant data. The flame zone shifts towards the inlet when using FPV model compared to the standard flamelet model, i.e. without progress variable. In both models the observed outlet values are in reasonably good agreement with the experimental values.
