Abstract

Fluidisation conditions in a circulating fluidised bed (CFB) can vary dramatically, from bubbling to circulating regimes. The granular Eurlerian models have been used to simulate the bubbling and slugging behaviour of gas-solid flows in CFB. Considering the dielectric properties and rapid movement of solids in CFB, electrical capacitance tomography (ECT) is particularly suitable for measuring the concentration and distribution of solids in CFB and for verifying simulation results. This paper reports the simulation results by computational fluid dynamics (CFD) analysis and experimental results obtained by ECT, and compares the simulation and experimental results first time, including the solids concentration profile, temporal variation of average solids concentration, auto-correlation coefficient and frequency spectrum.
