Abstract
The article presents the results of studying the stationary mode of cross-flow instability excited by a plasma actuator based on dielectric barrier discharge in a three-dimensional boundary layer on a swept plate with an induced pressure gradient. It is shown that the actuator generates an instability mode of a given wavelength with an initial amplitude of up to 2% of the free-stream velocity, while the signal-to-noise ratio is no greater than 15%. As a result of a parametric study, a family of growth curves of the excited instability mode was obtained as a function of the parameters of the voltage supplying the discharge. It is shown that the initial amplitude of stationary cross-flow vortices generated by the actuator in the studied range of parameters depends quadratically on the overvoltage at the electrodes and linearly on frequency, which coincides with a similar dependence for the actuator thrust.
期刊介绍：
High Temperature is an international peer reviewed journal that publishes original papers and reviews written by theoretical and experimental researchers. The journal deals with properties and processes in low-temperature plasma; thermophysical properties of substances including pure materials, mixtures and alloys; the properties in the vicinity of the critical point, equations of state; phase equilibrium; heat and mass transfer phenomena, in particular, by forced and free convections; processes of boiling and condensation, radiation, and complex heat transfer; experimental methods and apparatuses; high-temperature facilities for power engineering applications, etc. The journal reflects the current trends in thermophysical research. It presents the results of present-day experimental and theoretical studies in the processes of complex heat transfer, thermal, gas dynamic processes, and processes of heat and mass transfer, as well as the latest advances in the theoretical description of the properties of high-temperature media.
