Abstract: The paper considers several distinctive ideas of the “Plasma Aerodynamics”. A general approach is based on the reveal of main physical mechanisms of electrical discharges interaction with a high-speed gas flow: heating, electro-dynamic, magneto-dynamic, and chemical activation. The results of lab-scale experiments are discussed: drag reduction by in-front-of-body plasma generation; supersonic flow structure control by near-surface discharge; boundary layer actuation by dielectric barrier discharge (DBD); high-speed combustion intensification.
Typically, in-flow generated plasma appears as a non-uniform and unsteady formation. At some important cases unsteady plasma manipulation can give a large benefit in power consumption. The idea of plasma strong non-uniformity in space structure, non-equilibrium composition, and unsteady temporal behavior gives chance to decrease required energy deposition down to reasonable level at quite sufficient effect. Close problems are typical at attempts of plasma applications in a field of internal flows governing and high-speed combustion enhancement.
In each specific case the problem is arisen of suitable diagnostics application. In comparison with a gasdynamic test a quantity of parameters to be measured in plasma-assisted experiment is larger significantly. The conditions for diagnostic are more complex and some widely used methods are not applicable due to high level of EM noise, contaminations, extra radiation, high-amplitude electric field, and so on. The most used methods are applied in non-standard configurations or require a special adjustment.
The results of several experiments are presented to demonstrate abilities of electrical discharges for flow control. Specific experimental technique in Plasma-Assisted Aerodynamics is discussed as well.
