摘要
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 。
Chaotic characteristics of a gas-solid fluidized bed are analyzed using time series of pressure fluctuation in a gas-solid fluidized bed by this study. Meanwhile, based on the concept of mutual information in shannon information theory, the information transport between two pressure fluctuation time series is investigated in the reconstruction phase space, As a result, the authors argue that information is transferred three-dimensionally in the fluidized bed.
