針對海洋大氣邊界層中三維對流渦旋sar圖像,用g . s . young在2000年發表的方法,反演三維對流渦旋的特徵長度、海洋大氣邊界層高度、以及海洋大氣邊界層垂直對流尺度速度、表面浮力通量、海面風速穩定性校正因子和obukhov長度。The surface of propeller, hub and the vortex of blade is discreted by a number of small hyperboloidal quadrilateral panels with constant source and doublet distribution
槳葉、槳轂表面和螺旋槳尾渦面採用四邊形雙曲面元離散,以消除面元間的間隙。When f is about fr, for curved pipes, the secondary flow appears eight vortexes for annular cross section and four for circular and four or six for elliptical ; for helical pipe, the secondary flow appears as a loop flow for annular and circular cross section, and a saddle flow for elliptical cross section
當f在fr左右時,對于彎管,環形截面上存在八個渦,圓截面上存在四個渦,橢圓截面上存在四個或六個渦;對于螺旋管,圓截面和環形截面上二次流表現為環流,橢圓截面上表現為鞍流。In the second part of the paper, with employing the game reanalysis data and on the basis of the theories of the baroclinic vorticity development, this paper inferred from the dynamic analysis that the horizontal vorticity can represent the baroclinic intensity of the large - scale atmosphere, and the conversion of the horizontal vorticity converting into the vertical vorticity is actually the phenomenon that the horizontal vorticity flux of the summer monsoon owning the striking longitudinal - direction vertical structure and the strong baroclinicity, influence on the horizontal movement of the atmosphere
在第二部分,基於第一部分的結果,本文在斜壓渦度發展理論的基礎上,用在我國季風區具有更高準確性的game再分析資料,討論分析了能代表大尺度大氣斜壓性強度的水平渦度在向垂直渦度轉化的情況,說明了此轉化就是具有明顯經向垂直結構特徵和強斜壓性的夏季風環流圈將其經向垂直剖面上的渦旋通量強迫於水平運動的現象。Eventually mode a and b coexist in the wake, which confirms the previous studies. besides, the present paper finds that downstream the streamwise

在圓盤內部,氣體逐漸產生類似漩渦般密實的螺旋形運動,直到接近星體表面為止。The surface panel method has been applied to predict the hydrodynamic performance of highly skewed propeller. the surface of propeller and its trailing vortex are discreted by a number of small hyperboloidal quadrilateral panels with constant source and doublet distribution. for highly skewed propeller, the conventional method generating grid oriented along constant radii will result in a high aspect ratio and a high skewness and a twist panel near the propeller tip on blade surface, which result easily in incorrect calculation results of velovity on blade surface, even in iteration divergence and calculation failure. a “ non - conventional grid ” is developed to acoid these problems. this grid can effectively solve the problem of the calculation and convergence for highly skewed propeller. the non - linear kutta condition of equal pressure on upper and lower at the trailing edge is executed by the iterative procedure. by sample calculating, the obtained results are satisfied the experimental data
採用面元法預報大側斜螺旋槳水動力性能,螺旋槳表面及尾渦面離散為四邊形雙曲面元,每個面元上布置等強度源匯和偶極子分佈.對于大側斜螺旋槳而言,槳葉表面採用常規的等半徑網格劃分方法在近葉梢處將導致大展弦比、大側斜和扭曲面元,這容易使槳葉表面速度的計算結果不正確,甚至會導致迭代過程發散及計算失敗.文中建立了一種「非常規網格」劃分方法,能有效地解決大側斜螺旋槳的計算和收斂問題.槳葉隨邊處通過迭代實現非線性等壓庫塔條件Effects of leeside vortex isolation on pressure distribution over a high - alpha body of revolution
