Large eddy simulation of particulate flow inside a differentially heated cavity

Emmanuel Leriche, Michel Deville, Christoph Bosshard, Alfredo Soldati, Abdelouahab Dehbi

In nuclear safety, some severe accident scenarios lead to the presence of fission products in aerosol form in the closed containment atmosphere. It is important to understand the particle depletion process to estimate the risk of a release of radioactivity ...

Large eddy simulation of the differentially heated cubic cavity flow by the spectral element method

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

Large eddy simulations of the turbulent natural convection flow in a differentially heated cavity have been carried out at a Rayleigh number of 10(9) using the spectral element method. To obtain the large eddy simulation equations, a low pass filter given ...

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

Emmanuel Leriche, Michel Deville, Riccardo Puragliesi, Alfredo Soldati, 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, ...

Some issues concerning large-eddy simulation of inertial particle dispersion in turbulent bounded flows

Alfredo Soldati

The problem of accurate Eulerian-Lagrangian modeling of inertial particle dispersion in large-eddy simulation (LES) of turbulent wall-bounded flows is addressed. We run direct numerical simulation (DNS) of turbulent channel flow at shear Reynolds number Re ...

Appraisal of energy recovering sub-grid scale models for large-eddy simulation of turbulent dispersed flows

Alfredo Soldati

Current capabilities of Large-Eddy Simulation (LES) in Eulerian-Lagrangian studies of dispersed flows are limited by the modeling of the Sub-Grid Scale (SGS) turbulence effects on particle dynamics. These effects should be taken into account in order to re ...
