流线分离 meaning in English
on-line separation
Examples
- For both newtonian flow and non - newtonian flow , the vortices are generated when the waviness of the bottom profile is beyond a critical number . by increasing the waviness , a second vortex can be generated . with the increasing of reynolds number , the symmetry of the streamlines at re = 0 is destroyed and the vortices are sloped and become larger
当波形板的波动度超出临界值,波形板壁面上的流动出现流线分离,流动中有涡生成;增大波动度,流动中出现第二个涡; re = 0 ,流线在流场中对称分布;雷诺数增大,流线驻点在水平方向出现位置偏移,涡的范围增大;对于非牛顿流体,随着剪切变稀指数的减小,涡的作用范围减小。
