【摘要】 对气液固三相循环流化床中气固相含率沿轴径向的分布进行了实验研究和模拟。实验结果表明：与膨胀床相比，三相循环流化床内的相间接触较为充分；固含率轴向分布的一维沉降－扩散模型模拟值与实验值吻合较好。更多还原

【Abstract】 Distributions of gas and solid holdup along radial and axial directions are investigated and simulated. Experimental results indicate that compared with expanded bed, the three phase circulating fluidized bed can provide better interphase contact. One dimensional sedimentation dispersion model simulates the axial distribution of solid holdup well.更多还原
