Advances in Parallelization and High-Fidelity Simulation of Helicopter Phenomena

A weak and strong scaling study is presented which shows substantial improvements to the scalability of the CFD solver FLOWer by introducing a node-to-node MPI communication strategy. Furthermore, an overview of an extremely flexible and reusable CFD-CSD coupling interface is giving. It is able to handle unstructured, structured, and overset meshes without topology limitations and performance drawbacks. Finally, using these new capabilities a full helicopter configuration is investigated with regard to its aeroacoustic noise emission.
