متن کاملWeak entropy boundary conditions for isentropic gas dynamics via kinetic relaxation
We consider a kinetic BGK model relaxing to isentropic gas dynamics previously introduced by the authors, but with Dirichlet boundary condition on the incoming velocities. We pass to the limit as the relaxation parameter tends to zero by compensated compactness inside the domain, and obtain that the limit satisses entropy inequalities on the boundary involving weak traces of entropy uxes. Our m...
متن کاملRelaxation to Isentropic Gas Dynamics for a Bgk System with Single Kinetic Entropy
We introduce a family of vector kinetic BGK equations leading to isentropic gas dynamics in the relaxation limit, that have only one en-tropy at the kinetic level. These models possess the generic structure of kinetic relaxation models. By a sharp adaptation of averaging lemmas to BGK models that have a dissipative entropy, we establish an estimate in the inverse of the square root of the relax...
متن کاملFrom Kinetic Equations to Multidimensional Isentropic Gas Dynamics Before Shocks
This article is devoted to the proof of the hydrodynamical limit from kinetic equations (including BGK-like equations) to multidimensional isentropic gas dynamics. It is based on a relative entropy method; hence the derivation is valid only before shocks appear on the limit system solution. However, no a priori knowledge on high velocity distributions for kinetic functions is needed. The case o...
متن کاملWeak solutions for a hyperbolic system withunilateral constraint and mass
We consider isentropic gas dynamics equations with unilateral constraint on the density and mass loss. The and pressureless pressure laws are considered. We propose an entropy weak formulation of the system that incorporates the constraint and Lagrange multiplier, for which we prove weak stability and existence of solutions. The nonzero pressure model is approximated by a kinetic BGK relaxation...
