在雷诺数为106 ~ 107的高压风洞中对一个大圆柱进行了测量，结果表明，在雷诺数为3.5 × 106时，阻力系数从低超临界值增加到0.7，然后趋于恒定。当r>为3.5 × 106时，发生一定的涡脱落，其Strouhal数为0.27。
Measurements on a large circular cylinder in a pressurized wind tunnel at Reynolds numbers from 106 to 107 reveal a high Reynolds number transition in which the drag coefficient increases from its low supercritical value to a value 0.7 at R = 3.5 × 106 and then becomes constant. Also, for R > 3.5 × 106, definite vortex shedding occurs, with Strouhal number 0.27.
