- 論文の詳細を見る
The contribution of the particle flow (around and in a bubble) to the transfer mechanism of gas or heat between a bubble and the continuous phase was studied in a gas-solid fluidized bed. Two effects of particles were considered, that is, 1) the capacitance effect of particles flowing through the cloud and 2) of those falling in a bubble. Simple models were proposed for each effect. The validities of models were confirmed by experiments of gas adsorption and heat transfer, and it was confirmed that the volumetric fraction of particles in the bubble was εp=(1∼2)×10-3.
