  In this work, a high-order discontinuous Galerkin (DG) method is used to
perform a large-eddy simulation (LES) of a subsonic isothermal jet at high
Reynolds number Re D = 10^6 on a fully un-structured mesh. Its radiated
acoustic field is computed using the Ffowcs Williams and Hawkings formulation.
In order to assess the accuracy of the DG method, the simulation results are
compared to experimental measurements and a reference simulation based on a
finite volume method. The comparisons are made on the flow quantities (mean,
rms and spectra) and pressure far field (rms and spectra).
