turbulent boundary layer

基本解釋

As a result, roughly half the fuel required to maintain a level cruise is being burned to overcome the drag imposed by a turbulent boundary layer.
因此，保持巡航速度消耗的燃料大約一半都是用於尅服紊流産生的阻力。
During the computing model creating, emphasis are put on the calculation of input power from the turbulent boundary layer which is inhomogeneous to the sonar dome.

Mean velocity profile, turbulence intensity profile, integral scale and wind spectra are the most fundamental characteristics that describe the atmospheric turbulent boundary layer flow.
平均速度剖麪，湍流度剖麪，積分尺度和風(fēng)譜是反映大氣湍流邊界層流動(dòng)的四個(gè)最基本的因素。
