Particle image velocimetry analysis with simultaneous uncertainty quantification using Bayesian neural networks
- Computer Science
- 2020
This is the first use of Bayesian neural networks to perform PIV, and it is found that BCNNs using interrogation region cross-correlation maps as inputs perform better than those using interrogation windows only as inputs and discusses reasons why this may be the case.
The leading-edge vortex over a swift-like high-aspect-ratio wing with nonlinear swept-back geometry
- EngineeringBioinspiration & biomimetics

The results showed that the acoustic contrast factor for these droplets was negative, as the droplets relocated to pressure antinodes during ultrasonic actuation, which was consistent with the idea that the shell thickness depends on the droplet size, rather than being constant.

Long-Duration Time-Resolved PIV to Study Unsteady Aerodynamics
- Physics, EngineeringIEEE Transactions on Instrumentation and Measurement
- 2010
The buildup of flutter is shown to exhibit complex dynamics that are heavily influenced by the flow-induced motion of the body, and features of the wake turbulence as a function of time are presented and shown to substantially vary.
Estimation of Unsteady Aerodynamics in the Wake of a Freely Flying European Starling (Sturnus vulgaris)
- Physics, EngineeringPloS one
- 2013
It is shown that unsteady aerodynamics are necessary to satisfy the drag/thrust balance by approximating the unsteadY drag term and may shed light on the flight efficiency of birds by providing a partial answer to how they minimize drag during flapping flight.

It is concluded that the birds do not use their tail to exploit vortices shed at the wing root during the downstroke, suggesting a more complex wake structure in birds than previously assumed and calls for more detailed studies of the flow over the wings and body.
