This paper presents a novel mesh-update technique for unsteady free-surface Newtonian flows using spectral element method and relying on the arbitrary Lagrangian--Eulerian kinematic description for moving the grid. Selected results showing compatibility of ...
In order to better understand the sources of numerical instabilities occurring in the simulation of time-dependent flows of viscoelastic fluids at high Weissenberg numbers, we have used various types of linear stability analyses. In complement to the limit ...
The temporal stability and effective order of two different direct high-order Stokes solvers are examined. Both solvers start from the primitive variables formulation of the Stokes problem, but are distinct by the numerical uncoupling they apply on the Sto ...
This paper presents the application of spectral element methods to simulate the time-dependent flow of viscoelastic fluids in non-trivial geometries using a closed-form differential constitutive equation. As an example, results relative to the flow of a FE ...
Bidimensional interaction of an oblique shock with a plane plate has been studied numerically using large eddy simulation (LES) and compared with experimental data. This case represents an idealized model of bidimensional air intake and constitutes a chall ...

ENO filters are developed and compared with classical ENO schemes, TVD filters, and classical TVD schemes. The amplitude of the numerical dissipation provided by the filtering pass is computed by means of the artificial compression method (ACM) switch and ...

This paper presents the development of spectral element methods to simulate unsteady flows of viscoelastic fluids using a closed-form differential constitutive equation. The generation and decay Poiseuille planar flows are considered as benchmark problems ...
Large Eddy simulation (LES) of shock/homogeneous turbulence have been performed at two different Mach numbers (1.2 and 2) with four different subgrid scale (SGS) models (Smagorinsky model, mixed scale model, dynamic Smagorinsky model, dynamic mixed model). ...
