摘要

朱庆山研究表明

把铁颗粒添加到粘性粉体中

在轴向磁场的作用下

铁颗粒能够成链.Penchev和Hristov研究了横向磁场中铁磁颗粒流态化后

指出横向磁场流态化的一个主要特征也是磁链流态化.不过

这些研究只注重磁场流态化的一些本征特征

没有考虑通过磁场的变化改变磁链长度和磁链运动的方式

进而改善流化的质量.可以设想

如果这样的磁链放在横向均匀旋转磁场中使其自旋

那么自旋的颗粒链就能够对流化的颗粒起到搅拌和混合的作用

因而能够提高流态化的质量.

Abstract

Iron - particle chain rotation was studied in water-iron-stainless steel particle fluidized bed under transverse rotating magnetic field. Experimental results showed that the bed behavior had two marked features:①Chains formed by iron particles under low rotating frecpiency; ②Vibrating fluidized bed caused by rotating magnetic field. The factors affecting chain length such as rotating frequency

magnetic field intensity

flow rate and particles addition

were reported.
