DNS of buoyancy-driven flows and Lagrangian particle tracking in a square cavity at high Rayleigh numbers

Michel Deville, Emmanuel Leriche, Alfredo Soldati, Riccardo Puragliesi, Abdelouahab Dehbi

In this work we investigate numerically particle deposition in the buoyancy driven flow of the differentially heated cavity (DHC). We consider two values of the Rayleigh number (Ra = 10(9), 10(10)) and three values of the particle diameter (d(p) = 15, 25, ...

Computational performance of a parallelized three-dimensional high-order spectral element toolbox

Michel Deville, Roland Bouffanais, Jonas Marcel Lätt, Christoph Bosshard

In this paper, a comprehensive performance review of an MPI-based high-order three-dimensional spectral element method C++ toolbox is presented. The focus is put on the performance evaluation of several aspects with a particular emphasis on the parallel ef ...

Lattice Boltzmann method for the simulation of viscoelastic fluid flows

Michel Deville, Nicolas Fietier, Orestis Pileas Malaspinas

The simulation of viscoelastic fluids is a challenging task from the theoretical and numerical points of view. This class of fluids has been extensively studied with the help of classical numerical methods. In this paper we propose a new approach based on ...

An iterative domain decomposition algorithm for the grad(div) operator

Michel Deville, Etienne Ahusborde

This paper describes an iterative solution technique for partial differential equations involving the grad(div) operator, based on a domain decomposition. Iterations are performed to solve the solution on the interface. We identify the transmission relatio ...

Spectral Elements Analysis for Viscoelastic Fluids at High Weissenberg Number Using Logarithmic conformation Tensor Model

Michel Deville, Nicolas Fietier, Azadeh Jafari

This study discusses the capability of the constitutive laws for the matrix logarithm of the conformation tensor (LCT model) within the framework of the spectral elements method. The high Weissenberg number problems (HWNP) usually produce a lack of converg ...
