    Effect of system rotation on turbulence with applications to turbomachinery article pay-per-view 25€/article

    €0.00

    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.

    Review of the VKI Doctoral Research 2009-2010 - Free download

    €1.00

    These proceedings aim at giving a snapshot of the research done at the time of the Symposium. Its content is not reviewed by an editorial board and is the property and responsibility of the candidates and their supervisory teams. The idea is to encourage all candidates to write papers on their research even if this research is still under development or if the associated results are only partial. The goal is to train on communication at the best level possible and to offer a yearly compilation of the research accomplished at the Phd level. Learn More
