The vortex simulated in this article include the shedding vortex induced by the vane trailing edge boundary layer, the endwall vortex generated by the endwall boundary layer interaction, the passage vortex generated by the rotor rotation, and the leakage vortex generated by the tip clearance flow
渦輪級內的渦運動包括:導向器葉片尾緣附而層引起的脫落渦;轉子通道內轉子的旋轉運動產生的通道渦;根腳區兩個端壁附面層干涉,形成的根腳渦;存在葉尖漏流時,出現的漏流渦。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。Practical analysis of crosswind resonance on large - span structures with cables based on energy
基於能量的大跨結構的旋渦脫落共振實用分析The new economy does not mean we ' ll never have anther recession or even a deflationary spiral
新經濟並不意味著我們將永遠擺脫新一輪的衰退或是避免落入通貨緊縮的旋渦。Under some conditions, vortices are alternately shed from each side of the cylinder, which induces the fluctuating forces acting on the cylinder. it decreases the operating time of the equipment. for the purpose of the long - term reliability and the safety designing of the industrial component and the theory of gas - liquid two - phase vortex street, gas - liquid two - phase vortex street is simulated by commercial software phoenics for the first
工業領域內存在著大量的氣液兩相繞流柱體的現象,一定工況下形成交替脫落的旋渦,誘發柱體受到脈動升力的作用,由此產生的疲勞損傷大大縮短了工業設備的使用壽命,為了促進氣液兩相渦街理論的發展和給工業設備的設計和安全運行提供充分的科學依據。分享友人
