摘要: Abstract Multi-scale analysis and non-linear were combined to investigate the hydrodynamics of fluidized beds with without horizontal tubes. Pressure fluctuations measured analyzed employing discrete wavelet analysis, recurrence plot quantification analysis. A systematic procedure was followed determine parameters. At low gas velocities, energy macro-structures reduces addition first tube then increases a second tube. However, there is no notable difference at high velocities. Determinism for bed tubes, which can be attributed periodic behavior bubbles. decreases tubes because breakage bubbles results in less behavior. The three methods used this study captured effects immersed on beds. Recurrence quantitative found powerful easy-to-use method that capture nonlinear characteristics much more quickly than conventional This thus effectively online monitoring hydrodynamic changes
