射流流化床煤气化炉中气固流动和传热、传质的CFD模拟研究

The two fluid model was used to simulate a jetting fluidized bed coal gasifier with the support of CFD (Computational Fluid Dynamics) software. The modeling results for the behavior of gassolid flow and the heat and mass transfer in the fluidized bed gasifier were discussed. It can be concluded that the gassolid flow behavior greatly influences the heat and mass transfer in the fluidized bed gasifier.
