Improving an Unstructured CFD Solver for Aeroacoustics Applications

This paper reports on the development of a computational methodology for the simulation of aeroacoustics problems. An acoustic analogy is adopted and a in-house threedimensional unstructured flow solver is coupled to the Actran/LA commercial finite element solver that uses a variational formulation of the Lighthill analogy. Numerical investigations are performed in order to assess the appropriate level of accuracy required for the computational fluid dynamics part of this methodology.
