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.
期刊介绍：
Fluid Dynamics is an international peer reviewed journal that publishes theoretical, computational, and experimental research on aeromechanics, hydrodynamics, plasma dynamics, underground hydrodynamics, and biomechanics of continuous media. Special attention is given to new trends developing at the leading edge of science, such as theory and application of multi-phase flows, chemically reactive flows, liquid and gas flows in electromagnetic fields, new hydrodynamical methods of increasing oil output, new approaches to the description of turbulent flows, etc.
