Bioinspired trailing-edge noise control
(American Institute of Aeronautics and AstronauticsAIAA Journal, 2017-01-01)
Strategies for trailing edge noise control have been inspired by the downy canopy that covers the surface of exposed flight feathers of many owl species. Previous wind tunnel measurements demonstrate that canopies of similar ...
The acoustic Green's function for swirling flow in a lined duct
(ElsevierJournal of Sound and Vibration, 2017-05-12)
This paper considers the acoustic field inside an annular duct carrying mean axial and swirling flow and with either acoustically hard or lined walls. The particular aim is to compute the Green's function, which is required ...
Stability analysis for n -periodic arrays of fluid systems
(Physical Review Fluids, 2017-11-01)
© 2017 American Physical Society. A computational framework is proposed for the linear modal and nonmodal analysis of fluid systems consisting of a periodic array of n identical units. A formulation in either time or ...
