摘要/Abstract

摘要： 本文研究了轴向磁场作用下C类物料的流态化行为，得出磁场能有效地阻止沟流的发生和限制气泡长大的结论．实验用双光纤探头测量三维流化床内气泡的平均大小，以所得到的气泡大小作为衡量流化质量的定量标准；借助CA5300系统及图象分析的方法对流化床内针状物大小进行了定量分析；并对前文导出的数学模型进行了求解，模型计算结果与实验结果基本相符．

Abstract: The fluidization behavior of group C powder in an axial uniform magnetic field has been studied.Experiments demonstrate that channels and bubbles can be eliminated effectively.Two optica1 fiber probes are used to measure the size of bubble in the bed and the bubble size decreases with increasing magnetic field intensity and magnetic powder fraction.The length of"chain",obtained by using CA5300 board and modular system,is found to be strongly influenced by the magnetic field intensity.Experimental data are in agreement with that of calculated results from the mathematical model.
