查询词典 wake flow

According to the understanding of the flow characteristics, a mechanism of formation of vortex streets has been proposed to be the absolute instability of the wake, and several methods of flow control have been developed and shown successful.

根据表面流动及尾流特性的研究结果，从流动稳定性的角度提出了尾流中涡街产生的机理，在于尾流中存在着绝对不稳定的区域。基于对流动特性的理解，从改变流动稳定性的角度，寻求各种流动控制方法。试验结果表明这些方法是成功的。

For gas flow past cylinder, the characters of flow field in different Mach number and Knudsen number condition were investigated, and especially for low Knudsen number cases, the results were compared with calculating results of Euler's equation. It showed that they are correspondent by comparing the characters of bow shock and wake. The convergence rates of different high resolution and implicit schemes were also investigated. The convergence behavior of the implicit WENO scheme developed in this paper is better than others. For gas flow past NACA 0012 airfoil, the calculating results were compared with results of experiment. It showed that the results of WENO scheme are of higher accuracy for the case with angle of attack.

在圆柱流场时，我们探讨不同马赫数且不同纽森数时的流场特性，并在低纽森数时，与那维尔-史托克方程式的计算结果比较，我们比较了弓形震波及尾流附近的特性，其结果是相当符合的，同时我们也比较不同高解析隐式算则的收敛历程，从收敛历程图可得到，本文发展出来的隐式WENO算则有较佳的收敛效果；在NACA 0012翼形的流场中，我们将与实验结果做比较，发现利用WENO算则计算的结果，对於具有攻角的流场，亦有相当高的准确度。

The features and developing trend of jet-wake flow and secondary circulation were analyzed by velocity and pressure field in meridional planes.

本文利用数值方法研究了静止圆柱和振动圆柱在不同流动条件下绕流流场的非定常性、不稳定性和非线性特征。

This method is also available for other problems of unsteady flow around complicated bluff bodies at medium or high Reynolds numbers and the results are used as reference for wake control The phenomena of the sinusoidally oscillating flow past a circular cylinder are also studied.

本文应用有限差分方法求解涡量-流函数形式的N-S方程，数值模拟了园柱瞬时起动后流动分离、旋涡生成、脱落以及随时间推进涡街产生和长期非定常演化过程，包括对称涡的生成，二次涡形成的α结构及卡门涡街等。

The results show that: 1 trashracks do not interfere with one another when the trashrack spacing-to-width ratio is not small than 4, 2 turbulent intensity of the wake flow for the trashrack with streamlined profiles is much small.

用该算法对大长宽比的钝体尾流三维超声波流速仪测量数据的分析表明：1钝体间距与宽度之比大於4时，钝体间的相互影响可以忽略不计；2流线型的钝体尾流紊动强度较小。

As such the mechanism of particle transfer in a fully developed wake can be explained as: move around vortexes and forward with wake flow.

因此粒子在充分发展尾流中的运动可以描述为：一边绕涡团运动，一边随涡团向尾部运动。
