On the performance of a high-order multiscale DG approach to LES at increasing Reynolds number

Autor: Eric Lamballais, Marta de la Llave Plata, Fabio Naddei

The variational multiscale (VMS) approach based on a high-order discontinuous Galerkin (DG) method is used to perform LES of the sub-critical flow past a circular cylinder at Reynolds 3 900, 20 000 and 140 000. The effect of the numerical flux functi

The variational multiscale (VMS) approach based on a modal discontinuous Galerkin (DG) method is used to perform LES of the sub-critical flow past a circular cylinder at Reynolds numbers 20 000 and 140 000, based on the cylinder diameter. The potenti

Numerical stability analysis and flow simulation of lid-driven cavity subjected to high magnetic field

Autor: Elie Hachem, François Bay, Luca Marioni

Publikováno v: Physics of Fluids
Physics of Fluids, American Institute of Physics, 2016, 28 (5), pp.057102. ⟨10.1063/1.4948433⟩

International audience; In this work we study the flow of a conducting fluid inside a two-dimensional square domain. The problem is solved by using a variational multiscale finite element approach. The study focuses on a high magnetic interaction par
