中文摘要 | 本研究發現於側流式捆線型同心套管熱擴散塔中提煉重水時,若令雙管作相反方向旋轉,可產生續流效應,進而提高分離效率。本文並推導出獲得最大分離度及最大產率之最佳管旋轉速度的計算公式。 |
英文摘要 | This study investigated the rotation of tubes in opposite directions to enrich heavy water in a transverse-flow concentric-tube thermal diffusion column inserted as a spacer in the annular region with a wire spiral, having a diameter equal to the annular spacing. Equations for the optimal speed of tube rotation to achieve a maximum separation and maximum output were derived. Instead of using a stationary column without a wire spiral, considerable improvement in performance can be obtained if a rotated wired column is employed, operating at the optimal speed of tube rotation to create a desirable cascading effect. |
