A performance model of bubbling fluidized bed hydrodynamics

Investigation of the bubble behaviour at the free surface of a large three-dimensional gas fluidized bed

“…In recent years, a number of investigators (Manno and Ruocco, 1989;Lim et al, 1990;Johnson et al, 1991;Cai et al, 1994;Gera and Guatam, 1995;Ramayya et al, 1996) have carried out analyses and experiments for determining the bubble characteristics. They have measured directly or estimated bubble flow rates in freely bubbling beds.…”

“…Therefore, the most important goal of the modeling is the description of bubble dynamics (Rowe, 1976;Werther, 1980;Manno and Ruocco, 1989;Cai et al, 1994). In determining the performance of fluidised bed combustors (FBCs), it is essential to know the behaviour of the bubbles at the free surface (Chiba et al, 1972;Mori and Wen, 1975;Allahwala et al, 1981;Werther, 1983;Yue et al, 1986;Mainland and Welty, 1995).…”
