Neda Ebrahimi Pour: Efficient high-order simulation of aeroacoustics from rigid body motion on massively parallel systems (STS, Vol. 6, Diss., 2021)

This work presents an efficient strategy to facilitate large-scale simulations of aeroacoustics induced by rigid body motion.

A Discontinuous Galerkin method, providing low dispersion and dissipation errors, is used to propagate the flowinduced acoustics. An embedded boundary method is deployed to model complex moving geometries. Both, flow field and geometry modeling can use the same discretization method. The combination with a partitioned coupling approach allows for efficient massively parallel simulations of multiple scales. The modeling method and the partitioned coupling are thoroughly investigated and used in a detailed simulation of a real-world three-dimensional engineering problem of a moving airfoil that disturbs the fl uid fl ow, resulting in acoustic waves.
