Generalized Flows Satisfying Spatial Boundary Conditions

In a region D in R-2 or R-3, the classical Euler equation for the regular motion of an inviscid and incompressible fluid of constant density is given by partial derivative(t)v + (v . del(x))v = -del(xP), div(x)v = 0, where v(t, x) is the velocity of the pa ...

Non-Linear Gyrokinetic Simulations of Microturbulence in TCV Electron Internal Transport Barriers

Olivier Sauter, Laurent Villard, Stephan Brunner, Emiliano Fable, Xavier Lapillonne

Using the local (flux-tube) version of the Eulerian code GENE (Jenko et al 2000 Phys. Plasmas 7 1904), gyrokinetic simulations of microturbulence were carried out considering parameters relevant to electron-internal transport barriers (e-ITBs) in the TCV t ...

Photon energy dependence of the light pressure exerted onto a thin silicon slab

Giovanni Boero, Franz-Karl Reinhart

We review the theory of ponderomotive forces of classical nonionizing electromagnetic (EM) radiation exerted on dispersive matter. Minkowski's EM energy and momentum density lack any dispersion term in contrast to Nelson's theory, where they are included n ...

Solution viscosity and flocculation characteristics of linear polymeric flocculants in various media

Jutta Christine Wandrey, David Hunkeler

Rheological characteristics of linear copolymers of acrylamide (AM) and acryloyloxyethyltrimethyl ammonium chloride (Q9), differing in molar mass and chemical composition, have been studied in distilled water (DW) and industrial water (IW) obtained from a ...

Parallel Algorithms for Fluid-Structure Interaction Problems in Haemodynamics

Alfio Quarteroni, Simone Deparis, Gilles Fourestey, Paolo Crosetto

The increasing computational load required by most applications and the limits in hardware performances affecting scientific computing contributed in the last decades to the development of parallel software and architectures. In Fluid-Structure Interaction ...

Gyrokinetic Simulations of Microturbulence in TCV Electron Internal Transport Barriers

Olivier Sauter, Laurent Villard, Stephan Brunner, Xavier Lapillonne

Using the Eulerian code GENE [1], gyrokinetic simulations of microturbulence were carried out under conditions relevant to electron-Internal Transport Barriers (eITB) in the TCV tokmak [2], generated under conditions of low or negative shear. For typical d ...

Polymer Viscoelasticity in Shear

Fabienne Meier

Polymer materials may exhibit significant viscoelastic behaviour under various type of deformations. A model that can describe various viscous behaviours in simple tension was proposed in a previous work of the laboratory of biomechanical orthopedics. This ...

Transitional cylindrical swirling flow in presence of a flat free surface

Roland Bouffanais, David Lo Jacono

This article is devoted to the study of an incompressible viscous flow of a fluid partly enclosed in a cylindrical container with an open top Surface and driven by the constant rotation of the bottom wall. Such type of flows belongs to a group of recircula ...

Subfilter-scale fluxes over a surface roughness transition. Part I: Measured fluxes and energy transfer rates

Fernando Porté Agel

A wind-tunnel experiment was designed and carried out to study the effect of a surface roughness transition on subfilter-scale (SFS) physics in a turbulent boundary layer. Specifically, subfilter-scale stresses are evaluated that require parameterizations ...
