Tube erosion modelling in a fluidised bed

摘要

The paper presents the results of a computational model of erosion in a fluidised bed and a corre- sponding erosion experiment. The experiment has been simulated using the CFX[CFX-F3D, Version 4.1, Flow Solver User Manual, Computational Fluid Dynamics Services, AEA Industrial Technology, Harwell Laboratory, Oxfordshire, UK, 1995] code with computational models of hydrodynamics (Hydrodynamic Model A and kinetic theory model) and erosion (Finnie and kinetic theory). The experiment has been Conducted at room temperature using a horizontal acrylic tube immersed in a rectangular fluidised bed for a Totla of 126 h of run.
