應用CFD方法模擬室內氣溶膠的傳輸與沉積

摘要：【中文摘要】 本文對采用基于CFD模型的氣溶膠傳輸與沉降的研究進行了綜述,詳細介紹了適用于室內氣溶膠傳輸與沉積模擬的數值方法,對比了采用歐拉法以及拉格朗日法的數學模型以及各學者對其進行的假設與修正。同時,給出了各個研究者采用上述模型進行室內氣溶膠模擬的實例并對其進行討論,得出了不同模擬方法研究氣溶膠傳輸及沉降的優勢以及存在的問題。 【英文摘要】 A brief review on the aerosol particle dispersion and deposition in enclosed environment using CFD method was carried.It compared the Eulerian and Lagrangian method used to simulate indoor aerosol transport in detail.The modifications of both models made by different researchers were also discussed.Then,some applications of using both models for predicting particle dispersion and deposition in enclosed environment cases were presented.At last,some conclusions on the pros and cons of the two simulation methods were given. 【中文關鍵詞】 氣溶膠; CFD; 模擬; 歐拉法; 拉格朗日法【英文關鍵詞】 aerosol particle; CFD simulation; Eulerian method; Lagrangian method
