“…Table 2.1. Sau et al (2007) concluded that variables such as the tapered angle affect the magnitude of the minimum fluidization velocity. Meanwhile, the bed height for this type of bed does not have a significant effect on the minimum fluidization velocity.…”

“…Sau et al (2007) determined the minimum fluidization velocity for a gas-solid system in a tapered fluidized bed (conical fluidized bed) and studied the effects that bed geometry, specifically the tapered angle, had on the minimum fluidization velocity. They used three different angles (4.61, 7.47, and 9.52 degrees) to observe their effects on minimum fluidization velocity.…”

“…Sau et al [3] used a gas-solid conical tapered fluidized bed to find the minimum fluidization velocity and the pressure drop across the bed. The dimensions of the fluidized bed at the bottom were 48, 42, and 50 mm, the top of the bed measured 132, 174, and 212 nun, and the column heights were 520, 504 and 483 nun, respectively.…”

“…In the recent past, fluidization in tapered bed is gaining importance in view of its potential application in gas-solid system involving continuously decreasing particle size in combustion and gasification of coal, reduction of iron ores [24], etc. Although some investigations have been carried out in conical bed [25,26]and tapered bed [27,28] for prediction of minimum fluidization velocity under ambient conditions, similar data at elevated temperature conditions in tapered bed are not available. In this present work, investigations have been carried out at elevated temperatures to obtain the correlation of minimum fluidization velocity (independent of bed voidage) in tapered bed for gas-solid system and the correlation has been compared with values obtained by equation of Sau et al [28] proposed for tapered bed in ambient conditions in gas-solid systems.…”
