摘要: Abstract A method is developed for hydrodynamics scale-up of gas-solid fluidized beds based on recurrence quantification analysis nonlinear time series pressure fluctuations. This an improvement the previous by including entropy fluctuations to list parameters. Experiments were carried out at varying conditions, e. g., bed diameter (5, 9, 15, 40 and 80 cm ID), particle size (150, 300, 400 600 μm), height aspect ratios (1, 1.5 2) superficial gas velocities (ranging 0.1 1.7 m/s) identify main parameters that influence dynamics develop a general interpretation results. By investigation effect operating entropy, quantitative empirical correlation proposed in It was shown this improves Glicksman’s beds.
