제목 | CFD simulation of solid and gas flows in a semi-dual fluidized bed gasifier |
초록 | The hydrodynamic behaviors of the solidgas flow inside a semi-dual fluidized bed (sDFB) gasifier were investigated using a computational fluid dynamics (CFD) method. A two-dimensional (2D) Eulerian-Eulerian multiphase model incorporated with kinetic theory of solid particles has been used to compute the unsteady flow of the solidgas mixture. The model was solved using a commercial CFD code (Fluent, USA). On the basis of the simulation results, hydrodynamics of the two-phase flow and the distribution of the bed materials inside the gasifier were examined. The effects of operating conditions on the internal and external circulation rates of bed material were then discussed. |
