Towards Adjoint-Based Trailing-Edge Noise Minimization Using Porous Material
In this paper, we present a discrete adjoint-based optimization framework to obtain the optimal distribution of the porous material over the trailing edge of a 3-D flat plate. The near-body strength of the noi...

Simulation of a Helicopter Engine Jet Including a Realistic Nozzle Geometry
of a helicopter engine jet at a Reynolds number of Re = 750,000 and a Mach number of M = 0.341 is performed. The influence of a realistic nozzle geometry on the jet properties is analyzed by using hig...

A Hybrid Discontinuous Galerkin-Finite Volume Method for Computational Aeroacoustics
A hybrid method for a fully coupled determination of aerodynamic sound is introduced. From the instantaneous velocity and vorticity, determined by approximate solutions of the Navier-Stokes equations, acoustic...
