steady-flow aerodynamics
解釋
定常流空氣動力學-
Accurate calculation of aircraft steady and unsteady aerodynamics and flutter characteristics, especially in the transonic speed range is a crucial problem for aircraft designers. it is very important for us to develop an efficient, accurate, robust navier - stokes / euler flow solver that could be used to study transonic steady and unsteady flowfields
飛行器的定常和非定常氣動力的準確數值求解及顫振特性研究，特別是跨音速范圍內的準確數值求解及研究，一直以來都是飛行器設計工作者必須面對的重要研究難題。 -
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。
