尾迹流 meaning in English
following wake
Examples
- Re = 200 is just beyond the critical reynolds number of mode a . the numerical results of the present paper indicate that the near wake at this supercritical reynolds number is in three - dimensional quasi - periodic laminar state with transitional behaviors
Re = 200是刚超过模式a的临界雷诺数，计算结果表明，此时近尾迹流场处于三维准周期层流状态。 - 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 .
在对上述两种流动形态的二维大涡模拟研究中，首先全面地分析了气相时均流场的速度、湍流强度的分布规律以及气相速度的脉动规律等并就部分数值模拟结果与实验结果进行了对比研究；分析了平面尾迹流场中近壁处旋涡拟序结构，全面和逼真地反映了近壁处旋涡的生成、发展和脱落的规律；描述分析了平面尾迹流和平面射流的全场流动旋涡拟序结构，从整个流场的角度反映旋涡的生成、发展、运动以及旋涡之间相互配对、合并的作用规律等。 - Large eddy simulation of gas - particle two phase turbulence was carried out , such as simulation of two - dimensional gas - particle two phase wake , two - dimensional gas - particle two phase jet and three - dimensional gas - particle two phase rectangular jet . in these works , les was adopted to simulate gas phase flow and lagrangian approach was utilized to simulate the particles " motion . a series of significant and interesting results were obtained
