Displacement thickness evaluation for semi-empirical airfoil trailing-edge noise prediction model
(Springer, 2016-02-01)
This study proposes a criterion for evaluating the turbulent boundary layer displacement thickness when predicting airfoil trailing-edge noise with semi-empirical methods. The boundary layer integral parameter is usually ...

Determination of local flow conditions and preliminary investigation on the validity of the PNoise code for large-size wind turbine
(Springer, 2018-10-01)
This paper summarizes the determination of more realistic local Reynolds and Mach flow numbers at the blades of a large-diameter, horizontal-axis wind turbine designed specifically for this purpose with the aid of the blade ...
Spanwise-coherent hydrodynamic waves around flat plates and airfoils
(2021-11-25)
We investigate spanwise-coherent structures in the turbulent flow around airfoils, motivated by their connection with trailing-edge noise. We analyse well-resolved large-eddy simulations (LES) of the flow around NACA 0012 ...
Análise do espectro de ruído aerodinâmico em perfis aplicados à conversão eólica
(Universidade Federal do Rio Grande do NorteBrasilUFRNEngenharia MecânicaEngenharia Mecânica, 2022-07-20)
This work does noise evaluations of the turbulent boundary layer - trailing edge noise of several airfoils as well as considerations about the performance at free transition and forced transition, with application on wind ...
Dynamics of the large-scale structures and associated noise emission in airfoil slats
(Cambridge Univ Press, 2019-09-25)
We investigate the slat narrowband peak noise generating mechanism. Unsteady flow data were generated by a lattice-Boltzmann-based commercial code for four configurations, accounting for variations of the airfoil angle of ...
