Abstract

The results of the measurements of the time-periodic controlled disturbances in an inhomogeneous flat-plate boundary layer are considered at Mach number 2.5. The disturbances were introduced using a high-frequency glow discharge. The electric power of the discharge has been constant chosen. The nonlinear downstream development of wave trains and a considerable effect of the unit Reynolds number on the nature of the disturbance interaction is found to exist under the experimental conditions. An analysis of the wave characteristics of the disturbances is carried out.

2.5马赫数条件下平板边界层人工流动非均匀区可控扰动非线性发展实验

考虑马赫数为2.5时非均匀平板边界层中时间周期扰动的测量结果。利用高频辉光放电引入干扰。放电的功率是恒定的。在实验条件下，发现波列的非线性下游发展和单位雷诺数对扰动相互作用的性质有相当大的影响。对扰动的波特性进行了分析。
