流化床内生物质石英砂双组分混合流动混沌递归分析
Chaotic recurrence analysis of two-component flow of mixed biomass particles and quartz sands in fluidized-bed
摘要
Abstract
Recurrence plot and recurrence quantification analysis were used to analyze the pressure fluctuation signal, and particle flow characteristics at different numbers of biomass, quartz sands and different gas velocities were investigated. The quartz sands with the diameter of 0.8 mm and cylinder-shaped biomass particles with both diameter and length of 10 mm were used as bed materials. In the bubbling section, the periodicity of the system decreased first and then increased with increasing proportion of biomass. In the slugging section, recurrence plots of signal had the same textural feature in the fluidized-bed before and after biomass was added. The bubbling section determinism and laminarity flow rate increased with increasing gas velocity, and significantly decreased at a low proportion of biomass, but entropy of the system decreased with increasing gas velocity. The slugging section determinism and laminarity flow rate had a small change and entropy of the system decreased with increasing gas velocity, showing opposite tendency from the one-component system.关键词
