Abstract In this paper, we develop and test a unified hybrid LES/URANS turbulence
model with two different Large Eddy Simulation (LES) turbulence models. The numerical
algorithm is based on the Boundary Element Method. In the existing hybrid LES/URANS
turbulence model we implemented a new Smagorinsky LES turbulence model. The
hybrid LES/URANS turbulence model is unified, which means that the LES/URANS
interface is changed dynamically during simulation using a physical quantity. In order
to define the interface between LES and unsteady Reynolds Averaged Navier Stokes
(URANS) zones during the simulation, we use the Reynolds number based on turbulent
kinetic energy as a… More >
