Publikováno v: Journal of Fluid Mechanics. 948

The flow of polymer solutions past solid obstacles or through porous media gives rise to rich physical phenomena over a wide range of spatial and temporal scales. Viscoelasticity, in particular, can induce a strong nonlinear response with an increase

N° ISSN : 2194-1009; International audience; We propose in this paper a second order discretization of the momentum convection operator for fluid flow simulation on staggered quadrangular or hexahedral meshes. The velocity is approximated by the R

Laminar unsteady flows of Bingham fluids: a numerical strategy and some benchmark results

Autor: L. Boscardin, J. C. Latché, D. Vola

Publikováno v: Journal of Computational Physics. 187:441-456

We propose a numerical method to calculate unsteady flows of Bingham fluids without any regularization of the constitutive law. The strategy is based on the combination of the characteristic/Galerkin method to cope with convection and of the Fortin-G
