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… More >
