CFD Simulation and Experimental Analysis of Fluidization in a Model of an Oxyfuel Fluidized Bed Boiler

Popis výsledku v původním jazyce

Abstract This contribution introduces the methods and tools allowing the validation of a CFD simulator of an oxyfuel bubbling fluidized bed boiler by means of measurements obtained from a laboratory-scale fluidization chamber. For simulations, a custom OpenFOAM solver is developed based on the Multiphase Particle-In-Cell framework for handling the fluid-particle and inter-particle interactions. Some of the solver design details are introduced. Thereafter, the experimental device and its operation are described. The experimental results in the form of video recordings of the fluidized bed subject to changing air flow rates are processed by automatic tools. Using this framework, a direct comparison with the simulation results is possible and the coefficients of the Harris–Crighton model of inter-particle stress are fitted to achieve agreement between simulations and experiment. Based on the results, some improvements of both the CFD model and the experimental methods are proposed.
