Turbulent fluxes over heterogeneous surfaces and the blending height
非均勻地表的湍流通量和摻混高度The additional sub - scale flux is mainly determined by the average grid value, coefficient of variation and correlations among the meteorology parameters. ( 2 ) the additional sub - scale turbulence flux is composed by two parts, one part is induced by the correlations among the transfer coefficient, surface temperature and soil humidity, another is caused by non - line relationship between the transfer coefficient and roughness, stability
( 2 )非均勻分佈引起的附加次網格地表湍流通量主要由兩部分組成:一是地表次網格上輸送系數和地表溫度、濕度的相關項,另一是由於模式中計算整體輸送系數時,整體輸送系數是地表粗糙度和穩定度的非線性函數所造成擾動項。To prove the accuracy of the mach number, and the parameter homogeneity of the design nozzle " s exit, cfd calculate has carried on the design results. under the condition of supersonic and hypersonic flow, and a certain range of temperature, and mach number, the conclusion of the influence of specific heat to nozzle design is drawn
為了驗證所設計的噴管出口馬赫數的大小和噴管出口流場的均勻性,採用nnd格式和b l湍流模型求解雷諾平均n - s方程,對設計結果進行了cfd驗算,得出了在一定溫度范圍內,超音速、高超聲速流動的條件下,不同馬赫數范圍內變比熱容對噴管型面和噴管出口馬赫數的影響。In the next part, after verifying the simplified computational method of turbulence, the movement of fibers in turbulent pipe flow was simulated by 3 - d integral method and simplified computational method of turbulence. it was found that the fluctuation of turbulence caused random of fibers " orientation and its distribution became broader as the re numbers increased
然後,在驗證了湍流的簡化方法的合理性后,利用三維分段計算方法和湍流簡化方法模擬了大量纖維粒子在管道湍流內的運動,得出的結果為:湍流的脈動速度導致了纖維的偏角趨于無序,且隨著re數的增加,纖維偏角的分佈越來越趨于均勻。分享友人
