Analytic solutions for reduced leading-edge noise aerofoils
(American Institute of Aeronautics and Astronautics2018 AIAA/CEAS Aeroacoustics Conference, 2018-01-01)
This paper presents an analytic solution for the sound generated by an unsteady gust interacting with a semi-infinite flat plate with a piecewise linear periodic leading edge. The Wiener-Hopf method is used in conjunction ...
Aerodynamic noise from rigid trailing edges with finite porous extensions
(Cambridge University PressJournal of Fluid Mechanics, 2018-02-10)
This paper investigates the effects of finite flat porous extensions to semi-infinite impermeable flat plates in an attempt to control trailing-edge noise through bio-inspired adaptations. Specifically the problem of sound ...
