中文拼音 [wènliúwùtǐ]
紊流物體
英文
turbulent body-
Based these researches acquired and using a mathmatical model, this thesis tries to research the contaminant concentration distributions of three - dimention indoor turbulent flow by means of computational fluid dynamics and heat transfer, and then works out the ventilation efficiency
本文企圖在前人的基礎上，通過建立相應的數學模型，用流體流動數值計算方法來模擬室內三維的紊態氣流中的污染物濃度分佈，進而分析計算室內的通風效率，得出通風效率較好的室內氣流組織形式。In the turbulent flow, the fluid ’ s physical parameters has the stochastic change along with the time and the space, it is very difficult to carries on its rate process ’ s precise computation and the simulation with mathematics method, but unstable condition navier - stokes equation regarding open canal current of water transient motion suitable
閘后水流經過加糙的海漫段時，其水流狀態屬明渠紊流。流體中的各種物理參數，都隨時間與空間發生隨機的變化，很難用數學的方法對其運動過程進行精確計算和模擬。It uses the software of phoenics, imitating stratified air distribution of three - dimension turbulence in large space at many kinds of working at in k e pe in bo at arch wi m for ndds cut ords ed as pe of air ~ for wt pe of - w op of ~ nd we ch de ^ t wt the pe pe the pe ed co the bo of mp nd - - ds the for for the nd ~ or ~ for ds in tw pe bo inedwh edfor bo an all chwt to gr - - rpwhthe ~ oftw -, so ihat it co ha the ed ofds be all ghthemeedch
使用phoenics軟體，對多種工況下高大廠房大空間分層氣流組織進行三維紊流模擬。主要研究了高大廠房內的水平隔斷氣流，分析送風噴口類型、送排風口位置、障礙物高度、地面干擾氣流等因素對隔斷氣流的影響。在經濟性和實用性上得到最優化的結果，為大空間變動塵源復雜氣流的優化組織研究提供了參考。
