传感器所在截面处互相关系数的分布 Fig. 5 Correlation coefficient distribution in cross section of sensors at different fluidization air flow rates 图6 流化气体流量为7 m3/h时流化床中心处与床壁附近的相关速度 Fig. 6 Correlation velocities in center and near wall when fluidization air flow rate is 7 m3/h 图7所示为传感器所在截面固体颗粒的轴向速度分布.从图7可以看出:随着气流量增加,固体颗粒的轴向速度随之增加.并且颗粒的速度分布表明中间区域颗粒流速较高,而床壁附近的流速较低.产生以上结果的原因是:随着流化气量的增加,导致气泡的上升速度增加,由......
mm,低气速时生物质的添加对压力脉动信号的影响较大,表现为低生物质添加量下功率谱频率分布较均匀,幅值减小;高气速下生物质的添加对压力脉动信号几乎没有影响. 参考文献: [1] KUNII D, LEVENSPIEL O. Fluidization engineering[M]. 2nd ed. Portsmouth, UK: Butterworth-Heinemann, 1991: 1-7.
