dcterms:description
The work deals with the numerical solution of the 2D and 3D turbulent stratified flows in atmospheric boundary layer over the %22sinus hills%22. Mathematical model for the turbulent stratified flows in atmospheric boundary layer is the Boussinesq model - Reynolds averaged Navier-Stokes equations (RANS) for incompressible turbulent flows with addition of the density change equation. The artificial compressibility method and the finite volume method have been used in all computed steady cases. Lax-Wendroff scheme (MacCormack form) has been used to find the numerical solution and turbulence was modeled by the Cebecci-Smith algebraic turbulence model. Computations have been performed with Reynold's number 10^8 that corresponds approximatelly to the upstream velocity u = 1.5 m/s and with density range ρ є [1:2; 1:1] kg/m3 .
