dc.description.abstract | In the present work an approach for the simulation of aeroacoustic effects induced by the interaction of a turbulent flow with moving structures is presented. The aeroacoustic sound field computation is based on an acoustic/viscous splitting approach. Acoustic radiation is computed based on the linearized Euler equations (LEE) and acoustic sources are derived from the incompressible flow field solution. An arbitrary Lagrangian-Eulerian (ALE) method is applied for coupling the fluid and acoustic fields with the mechanical field. The validity of this approach for acoustic simulations is shown using two classical acoustic test cases, which are extended to moving grids. Finally, the aerodynamic and acoustic effects induced by an oscillating cylinder in a turbulent flow are presented. |
