This thesis is devoted to the development of numerical methods to predict jet noise using Large-Eddy Simulation (LES). The LES approach used in this work relies on high-order low-dissipation and low-dispersion implicit finite-volume schemes for spatial discretization. It allows the direct calculation of acoustic sources in turbulent flows and the propagation of sound waves with accuracy. Two numerical methods are developed in order to facilitate the LES computations. The first method focuses on using wall modeling in the near-wall regions instead of resolving the boundary layers. An analytical wall model is combined with the high-order schemes for spatial discretization. A specific spatial discretization, based on a ghost cell reconstructio...
