Domain decomposition techniques and hybrid multiscale methods for kinetic equations

چکیده
In this note we consider the development of a domain decomposition scheme directly obtained from the multiscale hybrid scheme described in [7]. The basic idea is to couple macroscopic and microscopic models in all cases in which the macroscopic model does not provide correct results. We will show that it’s possible to view a Boltzmann-Euler domain decomposition method as a subset of the hybrid scheme if we impose the value of the relaxation parameter equal to zero in some regions of the computational domain. Applications to the two-dimensional BGK equation is presented to show the performance of the method.

Fluid Solver Independent Hybrid Methods for Multiscale Kinetic Equations
In some recent works [11, 12] we developed a general framework for the construction of hybrid algorithms which are able to face efficiently the multiscale nature of some hyperbolic and kinetic problems. Here, at variance with respect to the previous methods, we construct a method form-fitting to any type of finite volume or finite difference scheme for the reduced equilibrium system. Thanks to ...

MULTISCALE–HYBRID–MIXED METHODS ALEXANDRE L. MADUREIRA Dedicated to Leo Franca, in memoriam. ABSTRACT. In an abstract setting, we investigate the basic ideas behind the Multiscale Hybrid Mixed (MHM) method, a Domain Decomposition scheme designed to solve multiscale partial differential equations (PDEs) in parallel. As originally proposed, the MHM method starting point is a primal hybrid formula...
متن کاملA hybrid method for hydrodynamic-kinetic flow - Part II - Coupling of hydrodynamic and kinetic models
In this work we present a non stationary domain decomposition algorithm for multiscale hydrodynamic-kinetic problems, in which the Knudsen number may span from equilibrium to highly rarefied regimes. Our approach is characterized by using the full Boltzmann equation for the kinetic regime, the Compressible Euler equations for equilibrium, with a buffer zone in which the BGK-ES equation is used ...
متن کاملA Hierarchy of Hybrid Numerical Methods for Multiscale Kinetic Equations
In this paper, we construct a hierarchy of hybrid numerical methods for multi-scale kinetic equations based on moment realizability matrices, a concept introduced by Levermore, Morokoff and Nadiga in [15]. Following such a criterion, one can consider hybrid scheme where the hydrodynamic part is given either by the compressible Euler or Navier-Stokes equations, or even with more general models, ...
متن کاملMOX–Report No. 12/2009 Coupling Biot and Navier-Stokes equations for modeling fluid-poroelastic media interaction
The interaction between a fluid and a poroelastic structure is a complex problem that couples the Navier-Stokes equations with the Biot system. The finite element approximation of this problem is involved due to the fact that both subproblems are indefinite. In this work, we first design residual-based stabilization techniques for the Biot system, motivated by the variational multiscale approac...
