Eulerian–Lagrangian Method for Three-Dimensional Simulation of Fluidized Bed Coal Gasification
In this paper, a comprehensive three-dimensional numerical model has been developed to simulate the coal gasification in a fluidized bed gasifier using a multiphase particle-in-cell (MP-PIC) method, and the formation of flow patterns, profiles of particle species and gas compositions, distributions of reaction rates and consumption of carbon mass were investigated under different operating conditions.
