    • A sensitivity based optimization approach for aeroacoustic problems 

      Nowak, Stefanie; Sternel, Dörte C.; Schäfer, Michael (CIMNE, 2015)
      Conference report
      Open Access
      This 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 

      Staab, Dominik; Nowak, Stefanie; Sternel, Dörte C.; Schäfer, Michael (CIMNE, 2015)
      Conference report
      Open Access
      Noise 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 

      Flitz, Frank; Sternel, Dörte C.; Schäfer, Michael (CIMNE, 2011)
      Conference report
      Open Access
      We 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 ...
