本文在气固流化床起流到快速流化的宽范围内研究了压力脉动时间序列的混沌特性参数随气速的变化趋势。同时应用Shannon信息理论 ,研究了床内不同测压点时间序列之间的信息传输关系 ,提出了信息是通过床内粒子扰动三维传输的观点
In this paper, the chaos characteristics of pressure pulsation time series are studied with the change of gas velocity in the wide range of gas-solid fluidized bed from fast-flowing to rapid fluidization. At the same time, Shannon’s information theory is used to study the information transmission relationship between time series of different pressure-measuring points in bed, and the viewpoint that information is transmitted through three-dimensional particle disturbances in bed
