boundary layer separation

基本解释

The theoretical analysis and experimental results show that boundary layer separation will produce pressure drag.
理论分析和实验的结果说明：边界层分离将引起压差阻力。
The basic equations of the boundary layer for blade surface flow of arbitrary cyclical surface are established, and the rotating effect for boundary layer separation is analyzed.
建立任意廻转面叶片表面边界层基本方程组，分析边界层分离的旋转效应。
If the reference separation point approaches the outlet, the test results are satisfactory, which state that the practical position of boundary layer separation point will be close to the outlet.
若分离参考点接近于出口端，则可获得满意的测试结果，这说明边界层实际分离点的位置已经很接近于叶片的出口端。

Mizuno reckons that by reducing friction, keeping the flow orderly and delaying separation of the boundary layer, its new suits offer the average female swimmer 9.5% less drag than a conventional costume.
