Experimental and numerical study of parallel blade-vortex interaction

Abstract

Parallel Blade-Vortex Interaction is studied both via experimental wind-tunnel tests with wing models in a tandem setup and via LES simulations. A p-adaptive Local Discontinuous Galerkin approach is used, with a physically based refinement indicator and a dynamic anisotropic eddy viscosity model for subgrid scale turbulent stresses. The results validate the numerical tool and show its efficacy and efficiency in the simulation of BVI, succesfully extending the range of investigation of the experimental setup.
