Internship position for master students in computational aeroacoustics :

Two-way coupling between a compressible Navier-Stokes solver and an Eulerian solver and application to a 3-D Large Eddy Simulation relevant for aeronautical applications

 Current research activities

Supersonic jet noise :
 large eddy simulations
— compressible Navier Stokes equations in cylindrical coordinates
— low-dissipation and low-dispersion numerical methods, high order of accuracy
— mesh containing up to 500 millions of nodes
 acoustic components specific to supersonic jets such as broadband shock-associated noise and screech noise
 noise generation mechanisms
 frequency-wavenumber decompositions, comparison with analytical dispersion relations

Supersonic impinging jets :
 large eddy simulations
— compressible Navier Stokes equations in cylindrical or cartesian coordinates
— low-dissipation and low-dispersion numerical methods, high order of accuracy
— mesh containing up to 300 millions of nodes
 noise generation mechanisms
 aeroacoustic feedback mechanism between the nozzle lips and the flat plate
 Analytical modelling of the aeroacoustic feedback
