Pressure and flow characteristics of a gas phase spout‐fluid bed and the minimum spout‐fluid condition

Abstract

Flow regimes in a spout–fluid bed: A combined experimental and simulation study

“…The first regime map of a spout-fluid bed has been reported by Nagarkatti and Chatterjee (1974). Their regime map was based on visual observation, like most regime maps that have been published since then (He et al, 1992;Sutanto et al, 1985;Vukovic et al, 1984).…”

Hydrodynamics of Conical Spouted Beds Using Different Types of Internal Devices

“…These modifications mainly concern the geometry of the contactor and/or the gas inlet to the bed. Given the advanced knowledge of their hydrodynamics and applications, the spouted beds of rectangular section, also with rectangular gas inlet [1,2], the conical spouted beds [3][4][5][6][7][8][9] and the spout-fluid bed [10][11][12][13][14][15] which combines the advantages of the spouted bed and of the bubbling fluidized bed are worth mentioning.…”

Computational study of particle temperature in a bubbling spout fluidized bed with hot gas injection

“…A large number of experimental investigations have been carried out on spout fluidization to understand overall particle flow dynamics and their regimes of operations in spout fluidization; see [5,6,7,8,9,10]. Besides this, the spectral analysis of pressure drop fluctuations has been exhaustively studied in literature [11,12,13]. Hydrodynamics of spouted fluidized beds has been studied extensively both experimentally and computationally in the past using relatively simple one dimensional models [14,15,16].…”
