• 中文摘要： 本文探討液-液-固三相流體化床之萃取系統。提出以Danckwert邊界條件的分散模式來描述此流動系統之特性。建立一個能配合實驗數據估計系統參數的方法。本文亦探討分散相及連續相雷諾數對分散系數及修正雪伍德數的影響。結果顯示分散相及連續相雷諾數分別在130至400及10至120範圍內,分散系數及修正雪伍德數可分別以下兩式表示:Nd/sub 0/= 0.048Re/sub A//sup 0.294/Re/sub O//sup 1.299/ Sh/sub 0/=37.66Re/sub O//sup 0.423/
• 英文摘要： The extraction operation conducted in a liqued-liquid-solid three phase fluidized bed was studied. An axial dispersion model with Danckwerts' boundary conditions was proposed to describe the characteristics of the flow system. A method was established to estimate the parameters of the system with experimental data. The effects of the particle Reynolds number of the dispersion phase and the continuous phase on the dispersion number Nd/sub 0/ and the modified Sherwood number Sh/sub 0/ were explored. The results indicated that Nd/sub 0/ and Sh/sub 0/ were correlated very well by Nd/sub 0/=0.048Re/sub A//sup 0.294/Re/sub O//sup 1.299/ and Sh/sub 0/=37.66Re/sub O//sup 0.423/ for 130.ltoreq.Re/sub A/=400 and 10.ltoreq.Re/sub O/.ltoreq.120.
