解釋
定常流風洞-
In this paper i was in virtue of the fluent software, set up the geometrical model of jin ’ ao mansion and adjacent buildings, used non - equilibrium wall functions to deal with the problem which come from the near wall, used realizable k - turbulent model to simulate the steady flow around 3d high - rise buildings, we can get the distribution of mean wind pressure coefficient of the surface of jin ’ ao mansion and five aerodynamics components. they were compared with the data from the wind tunnel test, we found out the distance between the result of the wind tunnel test and numerical simulation in the acceptable range
本文以fluent軟體為平臺，建立金奧大廈及其周邊建築的計算幾何模型，近壁區採用非平衡壁面函數法處理，運用基於雷諾時均的realizablek -湍流模型進行高層建築三維定常風場數值模擬，獲得金奧大廈表面時均風壓系數分佈及基底五分量氣動力，並和風洞測壓試驗的結果及風壓系數積分計算的基底五分量氣動力相比較，發現兩者之間的差異在可接受的范圍之內。 -
So a generator of visible light steady - state surface targets and pulse point targets is developed, which offers targets for studying transient optical transmission effects of flow in high - speed wind tunnel
因此研製了可見光穩態面目標以及脈沖點目標發生器，該系統為在高速風洞中研究高速流場的瞬態光學傳輸效應提供目標。 -
The traditional ventilation system of railway tunnels is always designed by the steady flow theory model ( stm ), which leads to many problems, such as the energy consumption is too large, mechanical ventilation ca n ' t be operated in some tunnels and automatic control of ventilation system with energy conservation also ca n ' t be performed, etc. this paper does some detailed studies on tunnel ventilation control method combined with a tunnel ventilation project
針對目前隧道通風設計採用傳統恆定流動理論，造成隧道通風系統能耗太大，使部分隧道不能進行正常機械通風以及隧道通風系統無法實現節能的自動控制等問題，本文結合具體工程，對隧道通風控制方法進行了較為深入的研究。
