- It is found in this work that the Von Karman vortex street could be totally suppressed at low Reynolds number region after adding the control cylinder at proper position. 由实验之结果发现：在锥形圆柱流场之适当位置加入控制圆柱后，在低雷诺数可使其尾流之冯卡门涡街完全消失；
- The vortices, known as von Karman vortices, appear when the air flow is disturbed by an object standing in the way. 这些涡旋称为冯卡门涡旋,一般在气流受到障碍物扰乱情况下出现。
- The von Karman constant of sediment-laden flows is one of the important parameters reflecting the influence of sediment movement on the flow structure. 挟沙水流卡门常数是反映泥沙运动对水流结构影响的重要参数之一,本文回顾并讨论了挟沙水流卡门常数的计算公式及其影响因素。

- Later, make a 38-year-old on the mechanics and physics community to recognize the "Weichang equation," Von Karman, his mentor is also his. 后来38岁就弄出了力学和物理学界承认的“钱伟长方程”，他的导师冯 卡门也很赞赏他。
- Based on the von Karman strainexpressions for plates and the method presented by Bergan and clough([l]),theequilibrium and incremental equations for a nonlinear analysis are derived,whichallow the consideration of the effect of the stiffener eccentricity. 根据 Von Karman 大挠度板理论以及文献[1]所提出的方法,考虑了加筋偏心的影响,获得了非线性有限元分析所需的平衡方程和增量方程。
- By using the Von Karman thin plate theory and Boltzmann superposition principle, the nonlinear equations of viscoelastic thin plate with damage are derived and denoted by the mid-plane displacements. 基于Von Karman板理论和Boltzmann线性叠加原理,建立了以中面位移表示的含损伤粘弹性板的非线性控制方程。
- So the frequency can't be simply calculated by the frequency formula of Von Karman vortex street around cylinder because Karman's formula is independent of hydrofoil's attacking angle. 尾流内存在周期性很好的类似卡门涡列的流动现象，其频率与叶片绕流状况有关，随着叶片入流角增加而增大，且属于低频范畴，因此，不能简单地采用圆柱绕流卡门涡街的频率公式进行计算。
