Incompressible Navier-Stokes limit for the Enskog equation
K e y w o r d s K i n e t i c equations, Navier-Stokes system, Singularly perturbed problem, Hydrodynamic limit. The Boltzmann equation, in the hydrodynamic limit, as both the Knudsen number and the Mach number are of the same order and tend to 0, is consistent with the incompressible NavierStokes equation (set [1-a]). Our aim is to study the incompressible macroscopic limit for the Enskog kine...
متن کاملThe Modified Enskog Equation for Mixtures
synopsis In a previous paper it was shown that a modified form of the Enskog equation, applied to mixtures of hard spheres, should be considered as the correct extension of the usual Enskog equation to the case of mixtures. The main argument was that the modified Enskog equation leads to linear transport coefficients which are in complete agreement with the laws of irreversible thermodynamics. ...
متن کاملPhenomenological dynamics: From Navier–Stokes to chiral granular gases
This paper reviews the derivation of equations for slow dynamical processes in a variety of systems, including rotating rigid rotors, crystalline solids, isotropic and nematic elastomers, gels in an isotropic fluid background, and nematic liquid crystals. It presents a recent derivation of the Leslie–Ericksen equations for the dynamics of nematic liquid crystals that clarifies the nature of the...
متن کاملPredicting polydisperse granular segregation
Most granular materials in industrial applications and natural settings are size-polydisperse, but most models and simulations of segregation consider only bidisperse particle distributions. Here, we extend our recently developed theoretical advection–diffusion–segregation model to polydisperse particle distributions. To test the theoretical approach, we model and simulate grains log-normally d...
متن کاملA Second - Order Projection Method for the I ncom pressi ble Navier - Stokes Eq uations
In this paper we describe a second-order projection method for the time-dependent, incompressible Navier-Stokes equations. As in the original projection method developed by Chorin, we first solve diffusion-convection equations to predict intermediate velocities which are then projected onto the space of divergence-free vector fields. By introducing more coupling between the diffusion--{;onvecti...
