• 中文摘要： 本文以蒙地卡羅法模擬膠羽在稀溶液, 批式攪拌槽中之動態破裂情形。傳統之模型皆考慮膠羽在破裂過程中其體積為守恆; 本文則提出因間隙水之釋出而體積不應視為守恆量之觀念。吾人假設膠羽係由某一基本之構成單位所組成,每一組成單位伴隨著與其體積成定比例之水, 其破裂可以一連串之雙體破裂近似。在這些條件下, 間隙水之釋出量可以計算。文中, 破裂被視為一隨機事件。實驗數據顯示, 膠羽之破裂頻率, 最大穩定體積, 與膠羽之基本構成單位之伴隨水量皆與攪拌槽之平均能量消散有關。
• 英文摘要： An examination of previously published experimental results reveals that the volume of floc is not a conserved property during the course of its disintegration. The present work investigates, for the first time, the effect of releasing the interstitial water on the dynamic characteristics of flocs in a lean, baffled, stirred tank. Stochastic simulation is conducted based on the assumption that a floc consists of a number of unit flocs each carries of a fixed amount of immobilized water. When breakage occurs, a certain amount of interstitial water is released, and thus, the total volume of the dispersed-phase entities decreases as time proceeds. The maximum stable floc size, the amount of water carried by a unit floc, and breakage frequency are found to correlate with the mean energy dissipation inside the stirred tank.
