A Level-Set Based Cartesian Grid Method to Simulate In-Cylinder Flow
This work discusses the extension of a three-dimensional, strictly conservative Cartesian cut-cell based method to meet the requirements for the simulation of in-cylinder flow and other flows bounded by comple...

Numerical Investigation of the Combined Effects of Gravity and Turbulence on the Motion of Small and Heavy Particles
Numerical studies [1, 2] show that the influence of gravity and turbulence on the motion of small and heavy particles is not a simple superposition. However, in [3] it is shown that these studies may be artifi...

Partitioned Fluid-Structure Interaction on Solution-Adaptive Hierarchical Cartesian Grids
A solution-adaptive hierarchical Cartesian cut-cell method is validated for fluid-structure interaction problems involving rigid bodies. The response of a tandem configuration of elastically supported cylin...

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...

Numerical Investigation of a Porous Trailing Edge by a Zonal RANS/LES Simulation
A hybrid Reynolds-averaged Navier-Stokes (RANS)/large-eddy simulation (LES) approach for flows with porous surfaces is presented. For the two-dimensional geometry considered, a computationally cheap 2D-RANS si...

Numerical Analysis of the Turbulent Wake for a Generic Space Launcher with a Dual-Bell Nozzle
The turbulent wake of an axisymmetric generic space launcher equipped with a dual-bell nozzle is simulated at transonic ( \(Ma_\infty = 0.8\) and \(Re_D = 4.3\cdot 10^5\) ) and supersonic ( \(Ma_\infty = 3\) a...
