Abstract:
As no reliable CFD models for porous burners are available, a Computational Fluid Dynamics (CFD) based simulation model has been developed which is intended to serve as an innovative tool to extend the application of porous burners to biomass boilers and to support the development of this new application by CFD simulations. The model developed allows a realistic three-dimensional calculation of the combustion processes inside porous burners coupling gas phase combustion and the solid porous medium. Following the model development, a detailed validation of the new CFD model has been performed. The motivation for this work is to enable a targeted and cost-efficient computer-aided design and evaluation of porous burners as well of relevant influencing parameters in their performance.
