Exact coherent structures and shadowing in turbulent Taylor-Couette flow
Michael C. Krygier, Joshua L. Pughe-Sanford, Roman O. Grigoriev
We investigate a theoretical framework for modeling fluid turbulence based on the formalism of exact coherent structures (ECSs). Although highly promising, existing evidence for th…

Quantifying the unknown impact of segmentation uncertainty on image-based simulations
Michael C. Krygier, Tyler LaBonte, Carianne Martinez +5
Image-based simulation, the use of 3D images to calculate physical quantities, fundamentally relies on image segmentation to create the computational geometry. However, this proces…

A novel subcritical transition to turbulence in Taylor-Couette flow with counter-rotating cylinders
Christopher J. Crowley, Michael C. Krygier, Daniel Borrero-Echeverry +2
The transition to turbulence in Taylor-Couette flow often occurs via a sequence of supercritical bifurcations to progressively more complex, yet stable, flows. We describe a subcri…
