Numerical approximation of aeroacoustics induced by flow over a square cylinder

Marhan, Tomáš, Sváček, Petr

Similarity:

This study investigates the generation of aeroacoustic sound resulting from the interaction of flow with a square cylinder at a Reynolds number of 150 and a Mach number of 0.2. The analysis combines the Finite Volume Method (FVM) for fluid dynamics using the OpenFOAM framework with the Finite Element Method (FEM) for acoustics implemented via the FEniCS Python library.

Similarity:

We show that the smooth bounded channel flows of a viscoelastic fluid exhibit the following qualitative feature: Whenever the channel is sufficiently wide, any bounded velocity field satisfying the homogeneous equation of motion is such that if the flow stops at some time, then the flow is never unidirectional throughout the channel. We first demonstrate the qualitative property of the bounded channel flows. Then we show explicitly how a piecewise linear approximation of a relaxation...
