    The Direct-Hybrid Method for Computational Aeroacoustics on HPC Systems

    Classic hybrid methods for computational aeroacoustics use different solvers and methods to predict the flow field and the acoustic pressure field in two separate steps, which involves data exchange via disk I...

    Simulation of Transonic Airfoil Flow Using a Zonal RANS-LES Method

    This paper presents a method for a synthetic turbulence generation (STG) to be used in a segregated hybrid Reynolds-averaged Navier-Stokes (RANS)-Large-Eddy Simulation (LES) approach. The present method separa...

    LES of Turbulent Flows Trough 90°-Pipe Bends on NEC SX-4

    Oscillatory phenomena in turbulent flows through 90°-pipe bends are numerically investigated using large-eddy simulations on the NEC SX-4 of the High-Performance Computing Center Stuttgart (HLRS). Since the ra...
