Quick Overview

Advances in aero-thermodynamics, aero-elasticity and aero-acoustics largely
depend on the understanding of the flow structures, and the ability to control them.
The first lecture note reviews the various approaches that are being followed for
plasma flow control. The fundamental interaction mechanisms are presented together
with the challenges associated to their implementation depending on the flow regime.
A presentation on the mechanisms for the generation of momentum transfer using
offset dielectric barrier discharges follows, focusing on the physics of the breakdown
formation. The next lecture note addresses phenomenological models that can be used
in conjunction with CFD codes, from simple algebraic equations to complex set of
partial difference equations. The first part is concluded with the use of DBD actuators
in various applications for internal and extemal flow control, over a range of Mach
numbers from 0.1 to 3.5, in a wide static pressure range from 0.1 to 9 bar.
The second part of the proceedings starts with the analysis of the goveming
equations of glow discharges in supersonic and hypersonic flows. The estimations of
characteristics time scales in high speed flow highlight the influence of gas motion on
the electro-dynamic structure. The second course note demonstrates successful plasma
applications in the lab at high speed, for drag reduction, plasma-induced generation of
shock waves, and artificial flow separation. The third lecture note describes recent
experimental and computational research in identifying and modeling the gasdynamic
and therrnochemical processes of the plasmoid generation with micro—wave and laser
discharge.

The third part begins with the description of the physics of the flow separation control on airfoils with the nanosecond plasma discharge. The effectiveness is demonstrated experimentally up to Mach number 0.75. Kinetic models in nonequilibrium plasma are discussed as well as mechanisms of shear layer instability, I optimal location and frequency of actuation. The second read-i-n-g—note discusses the use of a drift-diffusion model with the Poisson equation for plasmadyanmics to I simulate direct current discharge and DBD. The final amelecoiitribution reviews the main requirements for airplane aerodynamics flow control. Applications of surface and arc plasmas for civil aircraft will be discussed (wing separations, wing tip vortex, I boundary layer delay and fixing, buffeting, jet exhaust noise

.

The final part is initiated with the formulation of a consistent set of goveming equations able to describe the physical phenomenology comprising the flow field of ionized gas mixtures and the presence of the electromagnetic field. The following lecture outlines the basics of non-intrusive techniques (LIF, DLAS MWI, ...) and their application during a specific test campaign with respect to the control of ionized I hypersonic argon flow in arc heated facility. The last lecture note considers multi—temperature drift—diffusion model and simplified quasi-neutral model of glow discharge for gas discharges in rarefied hypersonic gas flows.

These Lecture Series proceedings on Effect of system rotation on turbulence with applications to turbomachinary held at the von Karman Institute from September 20 to 23 and was edited by M. Bilka & P. Rambaud in 2010
