Numerical investigation of the effects of different leading - edge profiles on vortical flows over a double - delta wing 尖顶襟翼长度对三角翼前缘涡破裂的影响
2.
This is a highly tricky exercise because vortical flow fields act in a complicated ( what scientists call nonlinear ) manner , making prediction difficult 这可难了，因为涡流场的变化模式非常复杂（就是科学家所说的非线性变化） ，难以预测。

Boeing wants to use existing wing and tail control surfaces that shift up and down about 20 degrees in a coordinated fashion to disrupt the vortical flow 波音公司则利用现成的机翼与机尾控制面，让它们互相协调、上下移动20度，以扰乱涡流。
4.
The flow visualization indicates the primary cause of the phenomena to be a combination of mass transport and vortical structures induced by strong paraelectric and peristaltic electrohydrodynamic ( ehd ) body forces on the flow . the main jobs of this paper can be generalized as follow : 1 流动显示结果表明了该实验现象的初步原因，由于在自洽电磁场中等离子体的电流体( ehd )顺电力与蠕动力诱导了涡和能量输运所致。
