Flutter Instability in an Internal Flow Energy Harvester
L. P. Tosi, B. Dorschner, T. Colonius
Vibration-based flow energy harvesting enables robust, in-situ energy extraction for low-power applications, such as distributed sensor networks. Fluid-structure instabilities dict…
Dynamics and decay of a spherical region of turbulence in free space
Ke Yu, Tim Colonius, D. I. Pullin +1
We perform direct numerical simulation (DNS) and large eddy simulation (LES) of an initially spherical region of turbulence evolving in free space. The computations are performed w…
Dynamics of an inverted cantilever plate at moderate angle of attack
Cecilia Huertas-Cerdeira, Andres Goza, John E. Sader +2
The dynamics of a cantilever plate clamped at its trailing edge and placed at a moderate angle () to a uniform flow are investigated experimentally and numericall…
Lift Coefficient Estimation for a Rapidly Pitching Airfoil
Xuanhong An, David R. Williams, Jeff D. Eldredge +1
We develop a method for estimating the instantaneous lift coefficient on a rapidly pitching airfoil that uses a small number of pressure sensors and a measurement of the angle of a…
On the formation and recurrent shedding of ligaments in droplet aerobreakup
Benedikt Dorschner, Luc Biasiori-Poulanges, Kevin Schmidmayer +2
The breakup of water droplets when exposed to high-speed gas flows is investigated using both high-magnification shadowgraphy experiments as well as fully three-dimensional numeric…
Non-linear input/output analysis: application to boundary layer transition
Georgios Rigas, Denis Sipp, Tim Colonius
We extend linear input/output (resolvent) analysis to take into account nonlinear triadic interactions by considering a finite number of harmonics in the frequency domain using the…
