Bio-inspired canopies for the reduction of roughness noise
(ElsevierJournal of Sound and Vibration, 2016-12-22)
This work takes inspiration from the structure of the down covering the flight feathers of larger species of owls, which contributes to their ability to fly almost silently at frequencies above 1.6 kHz. Microscope photographs ...
Secondary instability and tertiary states in rotating plane Couette flow
(Cambridge University PressJournal of Fluid Mechanics, 2014-11-14)
Recent experimental studies have shown rich transition behaviour in rotating plane Couette
ow (RPCF). In this paper we study the transition in supercritical RPCF theoretically
by determination of equilibrium and periodic ...
