| dc.description.abstract | "本論文以計算流體力學(Computational Fluid Dynamics, CFD)雷諾應力模型(Reynold Stress Model, RSM)模擬流體在旋風分離器中的連續相紊流流態，並以使用者自定義函數(User-defined Function, UDF)計算離散相(Discrete Phase Model, DPM)的固體顆粒在旋風分離器中的分離效率、軌跡及受力行為，分析在流體速度分別為6.51 m/s、13/02 m/s、19.53m/s及25℃、100℃、200℃及300℃四種不同溫度下旋風分離器中流態的變化，並針對不同顆粒粒徑條件，分別以Moris - Alexander與Stoke - Cunningham兩種氣固拖曳模型計算顆粒分離效率，比較兩種模型間顆粒所受到的加速度。結果顯示高溫的操作條件下，流體徑向上的紊流強度差會降低，使顆粒被帶往旋風分離器壁面的機率下降，使得分離效率降低。在Moris - Alexander計算模型中，粒徑較小的顆粒因受到較強的徑向拖曳力，容易隨著流體離開旋風分離器，Stoke - Cunningham模型中考慮到小顆粒在流體間滑動的程度提高，造成顆粒所受到的拖曳力大幅下降，結果顯示以Stoke - Cunningham拖曳模型計算會有較高的分離效率。" | zh_TW |
