Abstract Experimental aeroacoustics is concerned with the estimation of acoustic source power distributions, which are for instance caused by fluid structure interactions on scaled aircraft models inside a wind tunnel, from microphone array measurements associated sound pressure fluctuations. In frequency domain aeroacoustic propagation can be modeled as random problem convected Helmholtz equat...

The lattice Boltzmann method (LBM) is a numerical simplification of the Boltzmann equation of the kinetic theory of gases that describes fluid motions by tracking the evolution of the particle velocity distribution function based on linear streaming with nonlinear collision. If the Bhatnagar–Gross–Krook (BGK) collision model is invoked, the velocity distribution function in this mesoscopic desc...
