Romani, G. (author), Grande, E. (author), Avallone, F. (author), Ragni, D. (author), Casalino, D. (author)This paper presents a computational study of flow incidence effects on the aeroacoustics of a propeller operating at low blade-tip Mach numbers. The numerical flow solution is obtained by using the Lattice-Boltzmann/Very Large Eddy Simulation method, while far-field noise is computed through the Ffowcs-Williams & Hawkings' acoustic...journal article 2022

Romani, G. (author), Grande, E. (author), Avallone, F. (author), Ragni, D. (author), Casalino, D. (author)This paper proposes a CFD/CAA-based approach to predict the aerodynamic performances and tonal/broadband noise radiation of low-Reynolds number propellers at engineering level. Broadband self-noise prediction of low-Reynolds number propellers is particularly challenging, due to the requirement for the employed computational method to emulate...journal article 2021

Stokkermans, T.C.A. (author)This research is on the aerodynamics of propellers in interaction. As a propeller is dependent on the flowfield it encounters, any disturbance in that inflow results in changes in loading on the propeller. This can result in propulsive efficiency changes and affect stability through generation of in-plane forces and out-of-plane moments. The...doctoral thesis 2020

Yang, Y. (author), Sciacchitano, A. (author), Veldhuis, L.L.M. (author), Eitelberg, G. (author)Abstract: The interaction between a propeller and its self-induced vortices originating on the ground is investigated in a scaled experiment. The velocity distribution in the flow field in two different planes containing the self-induced vortices is measured by particle image velocimetry (PIV). These planes are a wall–parallel plane in close...journal article 2017

Roosenboom, E.W.M. (author)The aim of the thesis is to measure the propeller slipstream properties (velocity and vorticity) and to assess the unsteady and instantaneous behavior of the propeller flow field at high disk loadings, zero thrust and thrust reverse using the image based measurement techniques. Along with its implementation of the techniques in industrial...doctoral thesis 2011
