• 中文摘要： 本研究首先分別以一稀薄流化床及一濃稠床量取可溶鹽類及微溶鹽類之晶體成長速率,然後以成長兩步驟模式分析數據而獲得各物系之質傳係數。在稀薄床中,質傳係數為一定值,與晶體大小或流速均無關,並符合由弗洛斯林方程式導出之相關式。在濃稠床中,質傳係數亦趨定值,並可用一修正之弗洛斯林方程式解釋之。
• 英文摘要： Crystal growth rates of soluble and sparingly soluble salts were measured in a lean and dense fluidized-bed crystallizer, respectively. Then, the mass-transfer coefficients for crystal growth were determined using the two-step growth model. In the lean bed, the mass-transfer coefficient is independent of crystal size and solution velocity and is correlated with a form derived from the Froessling equation. In the dense bed, the mass-transfer coefficient is also fairly constant, which can be explained by a modified Froessling equation.
