Strouhal number is calculated and compared for different channel spacings and with the Ali & Ramadhyani experimental data.

本文对两种不同间距的波纹通道中的流动进行了非定常的数值模拟,给出了间距和雷诺数对反映涡脱落频率的无量纲斯特劳哈尔数的影响情况,比较了二维和三维数值模拟的差别。

The computed mean drag coefficient and the Strouhal number agree well with the experiment.

用二阶投影法求解二维不可压粘性流体的N -S方程 ,计算了高雷诺数Re=1× 10 5下串列圆柱的非定常绕流 ,得到的阻力系数及斯特劳哈尔数与试验结果吻合良好 ,结合工程实际 ,用同一程序计算预测了钢管混凝土拱桥哑铃型拱肋的阻力系数和涡脱频

At the same time, the effects of the Strouhal number and maximal attack angle on the hydrodynamics performance of the flexible fin were analyzed.

同时计算分析了斯特劳哈尔数、最大攻角等参数对柔性鳍水动力性能的影响,建立了最大推力系数和最高推进效率所对应的参数区间,其中低St数的最高推进效率发生在低αmax,高St数的最高推进效率发生在高αmax。
