With regard to the axial and radial distributions of solid density and the internal particle circulation, this new mathematical model for fast fluidization is superior in clear physical concept and fewer parameters. 该模型综合考虑了固体颗粒在床内的轴、径向密度分布和颗粒的内循环流动,具有物理意义明确、模型参数少等优点。
Based on the literature's experimental data, the regularity of average voidage changing with the operating conditions and the gas-solid properties in the fast fluidized bed are predicted satisfactorily by using the two-channel model of fast fluidization. 本文综合分析了文献报道的实验数据,利用快速流态化气固两通道流动模型较好地预测了床层平均空隙率随操作条件及气固物性的变化规律。
However, the correlations in literature are based on the average method, and therefore not suitable for simulating the heterogeneous flow structure in fast fluidization. 文献中应用的关联式都基于平均方法,不再适用于模拟快速流态化系统的非均匀流动结构。
There are two regions in circulating fluidized bed ( CFB), the dense phase region at the lower part and the fast fluidization region at the upper part. 研究表明在循环流化床内存在着二个区域:下部的密相区和上部的快速区。
