This design can compress the airflow so much that the air reaches supersonic speeds of mach 3 .
这种设计可以压缩气流以便达到mach3的超音速。
However , when the airflow is turbulent , the boundary layer sticks to the ball for longer .
然而,当气流为湍流时,边界层维持时间较长。
Dust that cools a desert can change local airflow patterns and lessen the amount of rain that falls in surrounding areas .
使沙漠降温的尘埃能改变当地的气流模式,减少周围地区的降雨量。
This is partly because we have built our settlements in sheltered places ; partly because turbulence caused by the buildings interferes with the airflow and chews up the mechanism .
一方面是因为我们住在避风的地方,一方面是因为房子会干扰气流,影响发电机制。
The extra volume of the heater core and its hoses , as well as the airflow of the heater fan blowing across the core , may dissipate enough heat to get you home -- or to the garage -- without a meltdown .
" We are the first team to measure airflow within the lung , " says andreas fouras , biomedical engineer and senior author of the paper .
该文章的自身作者,生物工程师安德里亚斯佛若斯说:“我们团队首创了在肺内进行气流测量的方法。”
When one row on one side blows air at a higher pressure than the other it causes the airflow over the trailing edge on that side to bend up or down , in exactly the way that an aileron would , and the plane rolls accordingly .
" The snake creates lift using a combination of its flattened cross-sectional shape and the angle that it takes to the oncoming airflow , known as the angle of attack , " socha explained .
An oscillation in the climate in the form of la nia-a cooling of the surface temperature across the equatorial eastern-central pacific , causing big changes in airflow and weather patterns-is likely to have contributed to the droughts .
