Numerical simulation of an incineration power plant employing OpenFoam

The ESTOS model is an Euler-Euler-based approach for modeling pulverized coal combustion whose fundamental assumption is fluid dynamical and thermodynamical equilibrium among the phases, implying that local velocities and local temperatures don´t differ among the phases. Based on this, the particle phase’s treatment is equivalent to that of a species in single-phase modeling, and consequently just one set of transport equations for the two phases should be set. In the present work the ESTOS model has been implemented in OpenFoam, simulations on a combustion chamber have been performed and the obtained results have been compared both against experimental ones and against the corresponding implementation of the same model in commercial CFD Fluent for their corresponding validation. This project has been conceived as the first step of a long-term project in order to simulate an incineration power plant employing OpenFoam.
