信息传输矩阵在气—固流化床流型识别中的应用

Application of Information Transmission Matrix in Fluidized Regimes Identification of Gas-Solid Fluidized Bed

在互信息理论和涨落复杂性理论的基础上,首次将ITM矩阵引入气-固流化床的流型识别中。将矩阵平均值(MITM)用于指示流型,实验结果表明了MITM对气泡行为敏感,能够较好的指示充分鼓泡态。此外,MITM随气速的变化趋势从另一个侧面反映了气固两相运动的混沌特性。

Based on the mutual information and fluctuation complexity theory, the information transmission matrix is used to identify the different fluidized regimes of gas 梥olid fluidized bed for the first time. Results of the experiment suggest that mean of the matrix is sensitive to bubble behaviors and can well identify the fully bubble state. In addition, the trends of MITM changing with gas velocity reflect the chaos characteristics of dynamic behaviors.
