In low Mach number aeroacoustics, the well known disparity of scales makes it possible to apply efficient hybrid simulation models using different meshes for flow and acoustics, which leads to a powerful computational procedure. Our study applies the hybrid workflow to the computationally efficient perturbed convective wave equation with only one scalar unknown, the acoustic velocity potential. The workflow of this aeroacoustic approach is based on three steps: 1. perform unsteadyarXiv:2009.02341v1 fatcat:up573vlt45d25kfu7rx6qlk5ue
