CLASSIFICATION AND DETERMINATION OF FLOW REGIMES IN SPOUT-FLUIDIZED BEDS

摘要

Five main flow regimes in spout-fluidized bed, namely fixed bed, spout with aeration, spout-fluidization, jet in fluidized bed and slugging, and corresponding major frequencies translated from pressure signals in each flow regime were obtained by experiments. The quantitative empirical equations for distinguishing these flow regimes were also proposed by using spout-geometry-fluidization parameters.
