✦ Synopsis

the kinetic problem is rapidly too expensive, because it requires one computational cell per mean free path. To

The aim of this paper is to introduce and validate a coupled Navier-Stokes Boltzman approach for the calculation of hypersonic overcome such difficulties, many authors have recently rarefied flows around manoeuvering vehicles. The proposed strattried to use intermediate asymptotic models such as Buregy uses locally a kinetic model in the boundary layer coupled nett equations . through wall friction forces to a global Navier-Stokes solver. Dif-The solution proposed herein is quite different. It uses ferent numerical experiments illustrate the potentialities of the locally a kinetic model in the boundary layer coupled method.

We represent a new numerical method to solve the stationary Navier-Stokes equations in an unbounded domain. This technique consists in coupling the boundary integral and finite element methods. Moreover, we derive the variational formulation and well-posedness of the coupling method and provide the
