Effect of Process Conditions on Fluidization
KONA Powder and Particle Journal, 2015 The influence of process conditions such as temperature and the presence of fines on the fluidization behaviour of gas-fluidized beds is of major importance in industrial fluid bed processes, which are often operated at temperatures well above ambient ...

Fluidization Characteristics of a Centrifugal Fluidized Bed.
KAGAKU KOGAKU RONBUNSHU, 1993 遠心流動層は高ガス速度で運転でき, 微小粒子にも適用できるなど特長があるが, 層高が比較的低いためにガスの吹き抜けや部分的な流動化が起こりやすい.ここでは遠心流動層における流動化状態を, 流動化部と非流動化部に分けた部分流動化モデルを用いて, 理論的に検討し, 分散板に仕切を設け, 面積, 仕込量, 回転速度を変えて行った実験と比較した.その結果, ガス速度を変化させたときの圧力損失プロファイルの理論値と実験値が良好に一致した.これより, 遠心流動層では一部から流動化が始まり, 層全体に拡がる過程が説明できた.また, ガス流速による固定層割合の変化は, 部分流動化モデルで説明できた.この流動化状態の変化には, 粒子径や粉体物性の差が大きく影響することが判明した ...
