Influence of air distribution on flow field in freeboard area in a bubbling fluidized bed boiler

Popis výsledku v původním jazyce

One of the basic functions of the air distributor is to provide uniform fluidization and homogenous flow field above the bed. Thus demand of CFD simulation arises from needs to understand behaviour of the fluidized bed. Situation in this case is complicated by the trough-shaped air distributor. The paper deals with 2D CFD simulations of fluidized bed and confronts it with experimental measurements on pilot scale unit. Simulations and measurements are done under ambient conditions without combustion. Simplified geometry was built up in Gambit and CFD simulations are done by ANSYS FLUENT.
