It was an honor to give a flash talk at the National Academy of Sciences ⁦National Academy of Sciences⁩ last night on our piece from “in the wake” with ⁦Pari Riahi⁩ ⁦UMass Amherst⁩ that is on display at the Traveling Gallery of Fluid Motion ⁦⁦APS Division of Fluid Dynamics⁩.

In our work just published in Journal of Fluid Mechanics, 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.20…

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/1iIIO1LkSaIc…

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.jflu…

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 UMass Press and with contributions from 11 scholars.

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/article/S23…

Vortices that are formed during the tail-flip escape response of crayfish. From our paper in collaboration with Ethan Clotfelter, and our students Luis X de Pablo and Adrian Carleton, just published in [email protected]. Here is a link to the paper: academic.oup.com/iob/article/6/…

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/1jTL78MuOhJf…

We look forward to working on this new project supported by U.S. National Science Foundation at UMass Amherst in collaboration with Luca Caracoglia Northeastern U. to derive a model to predict the influence of turbulence on flow-induced instabilities of offshore wind turbine blades. nsf.gov/awardsearch/sh…
