中文摘要 | 液柱型類比模擬器被用來模擬帶域精煉程序中變異分佈係數對分離效率之影響。 液柱型類比模擬器操作過程中,只須調整帶域管截面積以符合變異分佈係數之變化,便能獲 得各試樣管之高度分佈,進而分離程序的模擬得以完成。本文討論包括類比模擬器之結構、 操作與數學表示式。此多行程帶域精煉模擬器所獲得的結果和數值解非常吻合。 |
英文摘要 | The effects of variable distribution coefficients on the separation efficiency in zone refining processes have been simulated by operating liquid analog simulators. During the operation processes of liquid analog simulators, properly adjusting the area of zone tube along the operating procedure to simulate the operation with variable distribution coefficients, will obtain the liquid level redistribution in ingot tubes, resulting in the simulation of separation processes. The structure, operation and mathematical representation of liquid analog simulators are discussed. Performance of the proposed multipass zone-refining simulators are in excellent agreement with numerical solutions. |
