Navier–Stokes characteristic boundary conditions (NSCBC) usually assume the flow to be
normal to the boundary plane. In this paper, NSCBC is extended to account for convection …

A generalized formulation of the characteristic boundary conditions for compressible
reacting flows is proposed. The new and improved approach resolves a number of lingering …

BOUNDARY conditions are a usual weak point of compressible solvers, especially for large
eddy simulations (LES) or direct numerical simulations (DNS) in the subsonic regime. For …

Pour réduire la consommation en carburant et respecter des normes anti-pollution toujours
plus sévères, les motoristes font de plus en plus appel à la combustion prémélangée …

A methodology to implement non-reflecting boundary conditions for turbomachinery
applications, based on characteristic analysis is described in this paper. For these …

At supercritical conditions, thermodynamics may become strongly nonlinear which is
reflected by large thermodynamic Jacobian values. This means that small variations in …

This paper describes a new boundary condition for subsonic inlets in compressible flow
solvers. The method uses characteristic analysis based on wave decomposition and the …

A boundary condition for lattice Boltzmann methods, based on the movement of information
through Euler characteristic directions, is developed. With respect to the similar conditions …

Injecting turbulence into computational domains is needed in many direct numerical
simulations or large eddy simulations. This task may become difficult in compressible …

Aeroacoustics simulations require much more precise boundary conditions than classical
aerodynamics. Two classes of non‐reflecting boundary conditions for aeroacoustics are …
