Unstable periodic motion in large eddy simulation of homogeneous, isotropic turbulence

We study unstable, time-periodic solutions in Large Eddy Simulation (LES) of Homogeneous, Isotropic Turbulence (HIT). The turbulence is forced at large spatial scales by an external body force which induces four vortex columns in a rectangular domain with periodic boundary conditions. The dissipation range dynamics is represented by the...

Aircraft Noise Simulation for a Virtual Reality Environment

Aircraft noise annoyance predictions based on traditional tools lack fidelity when modelling a single aircraft flyover. For evaluating annoyance of new procedures, different aircraft types or changing atmospheric conditions, a new modelling approach is necessary. A research effort has been initiated to develop a toolchain that links each of the...
