The present paper proposes a numerical/experimental investigation of the aerodynamics and aeroacoustics of an isolated low-Reynolds rotor.

Abstract
The present paper proposes a numerical/experimental investigation of the aerodynamics and aeroacoustics of an isolated low-Reynolds rotor. An experimental campaign is carried out to evaluate the flow field downstream of the rotor through PIV measurements, whereas two microphone arrays are adopted to characterize the noise directivity. The numerical analyses are performed by the combined application of a boundary integral formulation suitable for the potential aerodynamics solution around lifting/thrusting bodies and the Farassat 1A formulation for the evaluation of the radiated noise. Several operating conditions are tested. The results demonstrate a good agreement between numerical predictions and experimental measurements sets the basis for the creation of a wide database exploiting the potentiality of both approaches in the perspective of establishing low-cost methods to be used in the preliminary design of complex, innovative solutions. © 2023 First author et al.
