Computation of Airframe Noise using a Discontinuous Galerkin Method
Marcus Bauer, German Aerospace Center (DLR)

Airframe noise is generated through turbulence passing by the edges of rigid bodies. It plays an important role in many fields such as the design of quieter means of transportation. The goal of this work is to compute airframe noise of a complex two-dimensional airfoil configuration. It will be meshed with a flexible unstructured triangular grid using a Discontinuous Galerkin (DG) discretization of the underlying Linearized Euler Equations (LEE). A respective two-dimensional Fortran DG-code is being developed to this end. Test computations reveal that this code is working correctly so far. In the next step it will be extended as to allow for a non-uniform LEE mean flow
