RÉSUMÉ
This paper deals with the problem of specifying proper inlet boundary conditions for Large-Eddy
Simulations (LES) or Direct Numerical Simulations (DNS). One possible approach is the synthesis of artifical
turbulent fluctuations by the Turbulent Spot Method or Synthetic Eddy Method (SEM). Almost all current formulations
of the SEM and related methods suffer from the violation of the continuity constraint.
In the current paper, we present an improvement to retain the continuity-constraint even for strongly anisotropic
turbulent fluctuations.
