Interaction between a surface dielectric barrier discharge and transonic airflows

Samantha Pavon

The use of plasmas in aerodynamics has become a recent topic of interest. The potentialities of different types of plasmas are being investigated for low velocity and high velocity flow control, as well as for plasma-assisted combustion. Dielectric barrier ...

Static aeroelastic response of chiral-core airfoils

Alessandro Spadoni

Extensive research is being devoted to the analysis and application of cellular solids for the design of innovative structural components. The chiral geometry in particular features a unique mechanical behavior which is here exploited for the design of 2D ...

Inclusion of aerodynamic non-equilibrium effects in supersonic plasma jet enthalpy probe measurements

Christoph Hollenstein, Malko Gindrat

Low pressure plasma spraying (LPPS) is a thermal spraying technique that has found a niche for low oxidation products. It uses a low pressure environment (i.e:, chamber pressure between 2 and 90 kPa) and yields supersonic plasma jets. The enthalpy probe te ...

EDGE2D code simulations of SOL flows and in-out divertor asymmetries in JET

Richard Pitts

EDGE2D simulations show that high SOL flows can be generated when an additional radial convective transport is applied in the SOL and pedestal region along with a 'ballooning-like' poloidal variation in transport. This model produces an inward particle flu ...

Highly loaded compressor with boundary layer suction

Klaus Hubrich

An experimental and numerical investigation of boundary layer suction (BLS) on a transonic compressor blade has been conducted. The objective of the present work is to identify the possible benefit of boundary layer suction via a slot in the region of the ...

Characterization of supersonic low pressure plasma jets

Malko Gindrat

Low Pressure Plasma Spraying (LPPS) processes use a DC plasma jet expanding at low pressure for fast deposition of dense coatings in a controlled atmosphere. The LPPS technology is widely used industrially in particular in the aeronautics and medical indus ...

Acoustic goniometry

Eric Van Lancker

This work was motivated by the increasing need for acoustic localization systems. The various localization systems that were implemented during this PhD include localization of snow avalanches, artillery and supersonic aircraft in the infrasound domain, th ...

The medium response to an impulsive redistribution of charge in solid argon: molecular dynamics simulations and normal mode analysis

Majed Chergui

Excitation of the A(3ss) Rydberg state of NO leads to an extensive rearrangement of the environment, which was studied by classical mol. dynamics simulations and normal mode anal., using pair potentials from the literature. The medium response is independe ...

An algorithm for low Mach number unsteady flows

Michel Deville

An algorithm is proposed for the simulation of unsteady viscous stratified compressible flows. The advantage of the method is its capability to deal with a broad range of subsonic Mach numbers, including nearly incompressible flows, with a single modelling ...

Analysis of Fluid-Structure Interaction by Means of Dynamic Unstructured Meshes

Pénélope Leyland

This paper presents a computational analysis on forced vibration fluid-structure interaction in compressible flow regimes. A so-called staggered approach is pursued where the fluid and structure are integrated in time by distinct solvers. Their interaction ...
