NUMERICAL SIMULATION OF GAS-SOLID FLOW IN AN INTERNALLY CIRCULATING FLUIDIZED BED USING MULTIPHASE PARTICLE-IN-CELL MODEL

摘要：

　　This paper presents a numerical study of gas-solid flow in an internally circulating fluidized bed (ICFB).The gas and solid dynamics have been calculated using the multiphase particle in cell (MP-PIC) model with Barracuda Virtual Reactor being the numerical platform.The simulation was conducted under a similar condition to a physical model consisting of three, inter-connected fluidized bed chambers with the central chamber representing the reaction chamber (RX) and a chamber on each side representing heat exchanger chambers (HEX).The detailed solid and gas flow dynamics have been investigated in terms of solid flow patterns and gas pressure drop.The simulation results have been compared with physical experiments in terms of solid recirculation rate, which shows a good agreement with the experimental measurements.
