循环流化床中宏观非均匀结构的计算机模拟

SIMULATON FOR MACROSCOPIC HETEROGENEOUS STRUCTURE IN CIRCULATING FLUIDIZED BEDS

运用颗粒运动分解轨道模型模拟了循环流化床中的宏观非均匀结构，模拟结果给出了与实验结果相吻合的空隙率分布、颗粒速度分布及气体速度分布．因此，颗粒运动分解轨道模型能够用于循环流化床中的宏观非均匀结构的模拟。

Simulation of macroscopic heterogeneous structure in circulating fluidized beds has been carried out by using the particle- motion- resolution trajectocry model ) result lug in distributions of voidage, particle velocity and gas velocity that are consistent with experimental data available in the literature. It is suggested that the part ide- motion- resolution trajectory model is efficient for simulating the dynamic behavior of circulating fluidized beds.
