A hybrid method for the simulation of aeroacoustic effects induced by rigid body motion in turbulent flow
(CIMNE, 2019)
Conference report
Open AccessIn the present work an approach for the simulation of aeroacoustic effects induced by the interaction of a turbulent flow with moving structures is presented. The aeroacoustic sound field computation is based on an ... -
A method for multi-objective topology optimization of acoustic and fluid flow properties
(CIMNE, 2019)
Conference report
Open AccessA framework for multi-objective topology optimization is presented with the purpose to simultaneously optimize both fluid flow and acoustic quantities. The proposed method uses a coupled approach on fixed grids with immersed ... -
A sensitivity based optimization approach for aeroacoustic problems
(CIMNE, 2015)
Conference report
Open AccessThis paper proposes an approach for the sensitivity computation of an aeroacoustic problem via the solution of the continuous sensitivity equations. The equations are derived by differentiating the coupled system ... -
Numerical simulation of acoustics in heterogeneous media
(CIMNE, 2015)
Conference report
Open AccessNoise influenced by multiphase flows becomes an increasingly important issue. Numerical simulations can help for a better understanding of sound behavior within heterogeneous media. In this work, we present a coupled ... -
The influence of different time integration schemes in ale description applied to moving meshes
(CIMNE, 2011)
Conference report
Open AccessWe analyze the error introduced by the arbitrary Lagrangian Eulerian description on a deliberately moved mesh with a flow field which is steady in Eulerian description. As governing equations, the Navier-Stokes equations ... -
Towards interaction of elastic structures with turbulence induced acoustics at low mach numbers
(CIMNE, 2013)
Conference report
Open AccessWe present an approach for fluid-structure-acoustics interaction that aims at the low Mach number range and combines a splitting approach for the fluid, similar to the linearized perturbed compressible equations of Seo ...
