AeroSPEED: a high order acoustic solver for aeroacoustic applications
Alberto Artoni, Paola F. Antonietti, Roberto Corradi +5
We propose AeroSPEED, a solver based on the Spectral Element Method (SEM) that solves the aeroacoustic Lighthill's wave equation. First, the fluid solution is computed employing a…

A hybrid finite volume -- spectral element method for aeroacoustic problems
Alberto Artoni, Paola F. Antonietti, Ilario Mazzieri +2
We propose a hybrid Finite Volume (FV) - Spectral Element Method (SEM) for modelling aeroacoustic phenomena based on the Lighthill's acoustic analogy. First the fluid solution is c…
