Turbulent heat transfer in a channel partially filled by porous medium is investigated using direct numerical simulation of an incompressible flow. The consists three-dimensional Cartesian grid cubes, which has relatively high permeability. energy equation not solved the cubes. Three different heating configurations are studied. performed for bulk Reynolds number Reb = 5500 and Prandtl Pr 0.1. turbulent flow quantities compared with results Breugem Boersma [“Direct simulations over permeable...
The models considered are supposed to govern the motion of compressible fluids such as liquidvapor mixtures endowed with a variable internal capillarity.Several formulations and simplifications discussed, from full multi-dimensional equations for non-isothermal motions in Eulerian coordinates one-dimensional isothermal Lagrangian coordinates.Hamiltonian structures pointed out each case, they used study stability two kinds non-linear waves: solitary, or homoclinic waves, heteroclinic which...
Staging phenomena occur in a wide range of materials. In this work, we investigate the thermodynamic properties multilayer free-energy models, which includes both intralayer and interlayer interactions. We show that continuous screening effect for repulsive interaction between layers is necessary to predict occurrence staged phases, without nonphysical nonpure ones. Included phase-field formulation, high-order model allows simulate first time complex staging kinetics stage 3 2, 3/2 phase,...
A phase-field model for vesicles including hydrodynamics was presented in two and three dimensions [T. Biben C. Misbah, Phys. Rev. E 67, 031908 (2003); T. Biben, K. Kassner, 72, 041921 (2005)]. particularly important feature is that their membrane locally incompressible. In these works a tension field defined everywhere the bulk introduced order to fulfill local inextensibility. Here we reconsider original by treating phase as thermodynamic variable develop picture which consistent with...
We extend our recent work on phase-field model for vesicles [D. Jamet and C. Misbah, Phys. Rev. E 76, 051907 (2007)]---where only the membrane local incompressibility was treated---to situation where bending forces spontaneous curvature are included. show how general equations can be derived within a thermodynamic consistent picture. analyze form of energy, Helfrich force is treated as special case. The dynamical evolution equation here velocity field allows one to write down constitutive...
In the present paper, we introduce an arithmetical definition of discrete circles with a non-constant thickness and exhibit different classes them depending on lines. On one hand, it results in characterization regular integer parameters as well J. Bresenham's circles. As far know, is first latter one. other new circles, actually thinnest ones for usual connectedness relations.
In two recent papers [D. Jamet and C. Misbah, Phys. Rev. E 76, 051907 (2007); 78, 031902 (2008)], we considered a thermodynamically consistent model for vesicles membranes, where dealt, in the first paper, with membrane local incompressibility condition, while second one bending energy derivation of constitutive law composite fluid: ambient $\text{fluid}+\text{membrane}$. This is last paper this series focuses on elimination surface tension (inherent phase-field models), retaining model. We...
The flow induced by buoyancy forces on an oil inclusion in a cavity full of water is considered. While the density difference effect counteracted viscosity and surface tension, unsteady turbulent develops leading to strong interface shearing stretching with drop extraction collapse. final stage stratified configuration top which should be predicted numerical simulation.
