On the aeroacoustic properties of a beveled plate

E3S Web of Conferences, 2015
The flow around a beveled flat plate model with an asymmetric 25 degrees trailing edge with three rounding radii is analyzed using a Navier-Stokes based open source software package OpenFOAM in order to predict the aeroacoustic properties of the models ...
