中文拼音 [guōxuángěbìng]
渦旋合併
英文
vortex merging-
And then simulations of gas - particle two phase plane wake and gas - particle two phase plane jet were carried out by using this model. after numerical simulations of the two flow fields were finished, series of analytical work was done. first, the distribution of time - averaged velocity, turbulence intensity was analyzed, and some of the simulation results were compared with those of the experiments ; the coherent structure of vortices in the near wall region of the plane wake flow were studied by describing the evolution of the eddy structures, including the forming, developing and shedding from the wall of the vortices in the near wall region ; the coherent structure of vortices in the whole field was also studied, such as the forming, developing, moving, pairing and merging of the eddies etc.
在對上述兩種流動形態的二維大渦模擬研究中，首先全面地分析了氣相時均流場的速度、湍流強度的分佈規律以及氣相速度的脈動規律等並就部分數值模擬結果與實驗結果進行了對比研究；分析了平面尾跡流場中近壁處旋渦擬序結構，全面和逼真地反映了近壁處旋渦的生成、發展和脫落的規律；描述分析了平面尾跡流和平面射流的全場流動旋渦擬序結構，從整個流場的角度反映旋渦的生成、發展、運動以及旋渦之間相互配對、合併的作用規律等。The effects of jet velocity ratio and skew angle were addressed. several co - rotating minute vortexes on the turbulence boundary layer would coalesce together that leaded to a big vortex. the effect of the big vortex was greater than a single minute one
單排多個同向射流與主流作用所產生的獨立小渦旋將在流向下游發生合併，形成大渦旋，大渦旋對邊界層的作用效果要強于單個獨立小渦旋。
