Abstract

This paper discusses simulations of airfoil flows by use of computational fluid dynamics. In recent work large eddy simulations (LES) of airfoil flows have proved superior to detached eddy simulations (DES); by resolving the inflow turbulence the agreement with experiments is improved. The scope of the present paper is to reduce the computational costs of LES by implying the inflow turbulence to the computational domain immediately upstream of the airfoil by an actuator disk. Thereby, only a small part of the domain in the close vicinity of the airfoil has to be resolved by a fine mesh.
