Horizontal particle mixing in a free fluidized bed

Magnetic tracking of a fuel particle in a fluid-dynamically down-scaled fluidised bed

“…A fluidised bed may contain various types of solids, which in solid fuel conversion applications can be roughly categorised as: the bed materials (also called 'bulk solids'), such as fuel ash, make-up sand or active solids, such as catalysts or sorbents for sulphur capture [1][2][3][4][5][6][7][8][9][10][11]; and fuel particles [12][13][14][15][16][17][18][19][20][21][22][23][24]. Fuel particles are typically larger and lighter than the bulk solids, and their mass fraction typically represents only a small fraction of the total solids inventory.…”

Lateral solids dispersion coefficient in large-scale fluidized beds

“…Here, such a review on the values of D sr is updated. A list of experimental studies [6][7][8][9][10][11][12][13][14][15][16][17][18][19] with measurement conditions and results is collected (see the supplementary materials, listed in a table). More than a dozen of works altogether since 1980s are collected.…”

“…Hundred and thirty four sets of measured data from more than a dozen of studies since 1980s are plotted. The measured values are plotted against the predictions using the correlation proposed by Borodulya et al[7].…”

Lateral solid mixing in gas-fluidized beds: CFD and DEM studies

“…Most researchers define by means of an equation analogous to Fick's law of molecular diffusion (Borodulya et al, 1982;Liu & Chen, 2010;Oke et al, 2015;Shi & Fan, 1984), thus writing:…”
