2) radial distribution of solids hold-up
固含率径向分布
1.
The radial distribution of solids hold-up in the riser of the compound reactor was measured in different operating conditions by PV-4A optical fiber density apparatus.
结果表明,固含率径向分布整体上呈现中心小、边壁大的环-核结构分布特征;沿轴向向上,各径向位置上的固含率在颗粒加速区逐渐降低,在充分发展区趋于稳定,在颗粒约束返混区又有所升高;各径向位置上的固含率随表观气速增大或颗粒循环强度减小而减小,且均匀性变好;提升管上部流化床内颗粒静床高度只对颗粒约束返混区内固含率径向分布有影响,而对颗粒加速区和充分发展区的固含率径向分布影响较小;当表观气速较低或颗粒循环强度较大时,颗粒约束返混区上部局部固含率最大值出现在无因次半径φ=r/R=0。

以空气-水-石英砂体系为对象,研究了费托合成浆态床反应器中表观气速、平均淤浆浓度、床层轴向位置等因素对气含率、固体浓度轴向分布和粒径分布的影响,并通过实验得出了气含率与操作变量之间的关联式。
补充资料:单轴各向异性
单轴各向异性是磁晶各向异性的最简单形式,即自发磁化的稳定方向(或易磁化方向)平行于一特殊晶轴。如六方晶系钴的自发磁化方向平行于 C轴(见晶体结构),这就表现出强的单轴各向异性。磁性材料的单轴各向异性值一般都低于其磁晶各向异性值,为103erg/cm3量级。磁性材料经磁场热处理或强的冷加工而产生的感生各向异性,都属于单轴各向异性。
