This is Mobot mobot, an ocean sunfish (Mola mola) robot from our lab.

Here is a link to our paper in Bioinspiration and Biomimetics that discusses this robot: doi.org/10.1088/1748...

This is a video from our paper published in the Journal of Fluid Mechanics today. We show that vortex shedding can be induced in the wake of a cylinder forced to rotate periodically at Reynolds numbers as low as Re=1 for higher rotation rates.

This is a video based on the results we discuss in our paper just published in the Journal of Fluid Mechanics @cambup-scieng.bsky.social on the behavior of a flexible square prism in flow.

In our paper just published in “Computers in Biology and Medicine”, we explore the utility of Proper Orthogonal Decomposition in elucidating coronary flow dynamics in patient-specific arteries pre- (left in the sample video) and post- (right) stent placement.

This is an image from Umang Patel’s Gallery of Fluid Motion poster (gfm.aps.org). These are polymeric stresses in the wake of a flexibly-mounted cylinder placed in inertial-elastic flow. Viscoelasticity is increased in the left image.

This is from the first slide of my talk at the APS DFD on Monday: "T29.00007 : Kirigami sheets in disturbed flow".

I thought of a sneaky way to find my people on this thing.

Self-identify and I will add you...

See you at APS-DFD!

Here is a clip of a video we submitted to the Gallery of Fluid Motion APS DFD 2024. We place free-to-move cylinders in the wake of a rigid cylinder to see how they re-organize themselves.

The full video is here:

Why #ComplexitySci is fascinating?

#ComplexSystems are ubiquitous!🧬🦠🧫🔬🐠🦜🧠🌪️🧪
And provide an analytical framework to study the behavior of phys, bio, eco, human & artificial systems #AcademicSky

Nicely done!
It turns out that I have the perfect simulation to celebrate all the new people joining the blue butterfly platform! Welcome!
