Abstract: Abstract The use of unsteady incompressible-flow simulations has become very popular for aeroacoustic noise predictions at low Mach numbers, as it provides a good compromise between computational time and reliable predictions. The acoustic radiation of… read more here.

DOI: 10.1109/tmag.2019.2954071
Abstract: Integral formulations lead to full matrices that, despite the use of efficient low-rank approximation techniques, are impossible to be solved when the number of unknowns is large enough. To overcome this limitation, we propose a… read more here.
