Gyrokinetic simulations of turbulent transport: size scaling and chaotic behaviour

Laurent Villard, Stephan Brunner, Trach-Minh Tran, Alberto Bottino, Sébastien Jolliet, Ben McMillan, Xavier Lapillonne, Thibaut Vernay

Important steps towards the understanding of turbulent transport have been made with the development of the gyrokinetic framework for describing turbulence and with the emergence of numerical codes able to solve the set of gyrokinetic equations. This paper ...

Representative Volume Element Size of Elastoplastic and Elastoviscoplastic Particle-Reinforced Composites with Random Microstructure

Matteo Galli, Joël Cugnoni

With the progress of miniaturization, in many modern applications the characteristic dimensions of the physical volume occupied by particle-reinforced composites are getting comparable with the reinforcement size and many of those composite materials under ...

A note on the eigenvalues for equivariant maps of the SU(2) sigma-model

Roland Donninger

We numerically calculate the first few eigenvalues of the perturbations of self-similar solutions of the spherically symmetric co-rotational SU(2) sigma-model on Minkowski space. ...

Solution of the tunneling-percolation problem in the nanocomposite regime

Peter Ryser, Claudio Grimaldi, Thomas Maeder, Gianluca Ambrosetti

We noted that the tunneling-percolation framework is quite well understood at the extreme cases of percolation-like and hopping-like behaviors but that the intermediate regime has not been previously discussed, in spite of its relevance to the intensively ...

Air-water two-phase flow modeling of turbulent surf and swash zone wave motions

David Andrew Barry, Roham Bakhtyar, Amir Mehdi Razmi

Wave breaking and wave runup/rundown have a major influence on nearshore hydrodynamics, morphodynamics and beach evolution. In the case of wave breaking, there is significant mixing of air and water at the wave crest, along with relatively high kinetic ene ...

Air-water two-phase flow approach to simulate nearshore wave motion

David Andrew Barry, Roham Bakhtyar, Amir Mehdi Razmi

The two-dimensional two-phase Navier-Stokes equations, volume of fluid technique and a two-equation turbulence closure model were used to predict wave breaking and runup, and compared with experimental data. Comparison of the results with a corresponding s ...

Unified formulation for Reissner-Mindlin plates: a comparison with numerical results

Luca Tassinari

Analytical solutions to problems of solids mechanics are useful to test the accuracy and the precision of the numerical approaches. Problems such as shear locking or boundary layer can be better understood with the help of analytical solutions. However, it ...

On local nonreflecting boundary conditions for time dependent wave propagation

Imbo Sim

The simulation of wave phenomena in unbounded domains generally requires an artificial boundary to truncate the unbounded exterior and limit the computation to a finite region. At the artificial boundary a boundary condition is then needed, which allows th ...

Finite-element preconditioning of G-NI spectral methods

Alfio Quarteroni

Several old and new finite-element preconditioners for nodal-based spectral discretizations of −laplace(u) = f in the domain

\Omega = (-1, 1)^d

(d = 2 or 3), with Dirichlet or Neumann boundary conditions, are considered and compared in terms of bothcondi ...
