This work is devoted to the numerical solution of three-dimensional linearized Euler equations around steady-state, smooth, subsonic flows. In order to get symmetric matrices for these equations and, in fine, an energy balance equation, we consider the linearization of symmetrized Euler equations. We propose a non-dissipative Discontinuous Galerkin Time-Domain (DGTD) method which relies on an element-centered formulation with centered numerical fluxes and an explicit leap-frog time scheme, leading to a dissipation-free approximation and allowing an accurate estimation of the aeroacoustic energy variation. Indeed, in the general case of the linearization around a non-uniform flow, a balance equation with source term for the aeroacoustic ener...
