SUMMARY:Seminar in Numerical Analysis: Christophe Geuzaine (Université de 
 Liège)
DESCRIPTION:This talk is devoted to non-overlapping Schwarz domain decompos
 ition methods for the resolution of high frequency flow acoustics problems
  of industrial relevance. First\, we will present recent advances on non-r
 eflecting boundary techniques that provide local approximations to the Dir
 ichlet-to-Neumann operator for convected and heterogeneous time-harmonic w
 ave propagation problems [1]. Then we will show how to adapt a generic dom
 ain decomposition framework to flow acoustics\, based on these newly desig
 ned transmission conditions\, and highlight the benefit of the approach on
  the simulation of three-dimensional noise radiation of a high by-pass rat
 io turbofan engine intake [2].  [1] Marchner\, P.\, Antoine\, X.\, Geuzain
