We look forward to working on this new project supported by @NSF at @UMassAmherst in collaboration with Luca Caracoglia @Northeastern to derive a model to predict the influence of turbulence on flow-induced instabilities of offshore wind turbine blades. nsf.gov/awardsearch/showAwar…

The response of a closed-loop kirigami pattern in flow. The kirigami sheet undergoes a large elongation in the direction of flow, but despite this large elongation, the sheet does not experience any flow-induced instability. From our recent paper in EML: authors.elsevier.com/a/1jTL7…

This is a fractal-cut kirigami sheet placed in flow. The kirigami sheet buckles at higher flow velocities and passively controls the direction of jets that are formed downstream of the sheet. From our paper just published in Extreme Mechanics Letters: authors.elsevier.com/sd/arti…

Following Exactitude, published in 2022, comes Multiplicity: On Constraint and Agency in Contemporary Architecture, our second edited volume, co-edited with L. Katsaros and Michael T. Davis, published beautifully by @umasspress and with contributions from 11 scholars.

These are angular oscillations of a cylinder placed in flow. When the cylinder is allowed to oscillate in a convex orientation (right), it reaches larger amplitudes compared with when it is allowed to oscillate in the concave orientation (left). doi.org/10.1016/j.jfluidstru…

These elongated S-shaped vortices are shed in the wake of a flexibly-mounted cylinder that oscillates as it interacts with the incoming inertial-elastic flow. From our paper just published in the Journal of Non-Newtonian Fluid Mechanics: authors.elsevier.com/a/1iIIO…

In our work just published in @JFluidMech, we show a new mode of shedding in the wake of a cylinder forced to oscillate in viscoelastic flow, that is caused entirely by fluid's viscoelasticity. These are the elongated red and blue regions in the video. doi.org/10.1017/jfm.2023.861
