Recent advances in low-Reynolds number rotor aeroacoustics models
Damiano Casalino
Abstract: The keynote lecture will review the most recent achievements in Lattice Boltzmann simulations of low-Reynolds number rotor aeroacoustics with emphasis on transitional boundary layer mechanisms. The first part of the presentation discusses the experimental and numerical benchmarking challenges, by focusing on aspects related to the scale-resolving capabilities of the employed turbulence model, and to the effects due to flow recirculation in the test chamber. The second part of the presentation introduces a methodology for the calculation of unsteady forces and noise in variable RPM conditions. Finally, an overview of a flight mission analysis framework for eVTOL vehicles is presented.
