Abstract

A flexible hybrid approach is investigated for computing far-field jet noise. Compressible large eddy simulation based on a linear discontinuous Galerkin (DG) solver is used to com- pute the near-field flow. The far-field noise is computed using a Ffowcs Williams-Hawkings solver. Two variants for the degrees of freedom in the linear DG solver are considered and their impact on the implicit numerical dissipation tested. Both variants support arbitrary, approximately convex polyhedral elements. The overall method is applied to predict the far-field noise of a Ma = 0.9 cold turbulent jet including nozzle geometry. Comparisons with measured flow fields are reasonable, however preliminary noise predictions show excessive falloff in the high frequency range.
