This paper collects the state of the art and the tremendous progress that has been made in
hybrid modeling of aeroacoustic sound. Hybrid modeling is defined such that flow and …

We consider the second order wave equation in an unbounded domain and propose an
advanced perfectly matched layer (PML) technique for its efficient and reliable simulation. In …

In low Mach number aeroacoustics, the well-known disparity of scales allows applying
hybrid simulation models using different meshes for flow and acoustics, which leads to a fast …

Although many numerical simulation tools have been developed and are on the market,
there is still a strong need for appropriate tools capable to simulate multi-field problems …

A hybrid aeroacoustic approach was developed for the efficient numerical computation of
human phonation. In the first step, an incompressible flow simulation on a three-dimensional …

The hybrid aeroacoustic approach is an efficient way to address the issue of the disparity of
scales in Computational AeroAcoustics (CAA) at low Mach numbers. In the present paper …

The aerodynamic characteristics of a hyperloop vehicle with or without channels operating
at subsonic speeds in a low-pressure tube were simulated using a scale-adaptive simulation …

The aeroacoustic mechanisms in human voice production are complex coupled processes
that are still not fully understood. In this article, a hybrid numerical approach to analyzing …

Acoustic data has long been harvested in fundamental voice investigations since it is easily
obtained using a microphone. However, acoustic signals alone do not reveal much about …

A hybrid aeroacoustic formulation, which is well suited for the computation of rotating
systems, is presented. It is based on a decomposition of flow (incompressible part) and …
