Abstract
This contribution focuses on CFD modeling of the dynamics of the bubbling fluidized bed under conditions specific for oxyfuel combustion. A custom OpenFOAM solver is developed based on the Multiphase Particle-In-Cell framework for handling the fluid-particle and inter-particle interactions. Features of this Euler-Lagrange approach are discussed, and some of the solver design details are given. Some simulation results of a laboratory-scale combustion device or its combustion chamber are demonstrated, showing the capabilities of the solver. The current limitations and plans for further development are also included.
