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 ...
