摘要
变湍流度试验结果表明，湍流度对诸如洞壁边界层、平板边界层、各类翼型边界层和尾流的时均特性、湍流特性、转捩情况以及对翼型和旋成体压力分布等气动特性有显著影响。这种影响有一定规律，量值较大，不能忽视。
The test results at variable wind tunnel turbulence has shown that the turbulence level has large effects on the boundary layer transition, time average and turbulent characteristics for the boundary layer of wind tunnel wall, flat plate and different types of air foils. Turbulence level also has large effects on the pressure distribition of bodies, such as airfoils, bodies of revolution etc. The effect of turbulence is large, and has certain rule, so it can't be ignored.
