Analyzing Quadcopter Drone Propeller Noise Using Ansys CFD
This webinar will discuss the use of Ansys Fluent to simulate the noise produced by a generic four-bladed quadcopter drone. The methodology is based on the use of unsteady scale-resolving turbulence modeling along with the Ffowcs Williams-Hawkings (FW-H) acoustic analogy to compute sound pressure levels at selected locations below the drone. Acoustic FFT results from the CFD simulation will be presented showing how the acoustic tones and broadband noise change with position relative to the vehicle.
In addition sound analysis tools from Ansys Sound will be applied to the acoustic results to help assess psychoacoustic parameters associated with the perceived sounds and to demonstrate the generation of audio files which allow you to listen to the simulated noise.
