Nature's elegance >>>>

I’m having an especially hard time concentrating on research this week, but instead of doomscrolling on twitter I guess I’ll do something semi-productive and make another twitter thread. Today's topic: What is a Lyapunov function? 1/

Happy Valentines Day everyone! Hope our cut-cell #CFD #Simulation can be a gift during the lockdown...

Been working on characterizing a new gust generating system using PIV. Jets make for super cool Gifs.

More cool flow viz! This is the outlet of a gust generator which creates a vertical water jet. Upon the start of the jet, the flow rolls up and around around the edges of the outlet (black rectangle), and creates a pair of vortices. #aerodynamics #vortex

Experimental PIV images of a wing pitching in a vertical gust. The pitching maneuver aims to negate the effect of the gust. #aerodynamics

This video by Temasek Laboratories shows a morphing-wing model performing an excerpt of the Waltz of the Flowers from The Nutcracker suite by Tchaikovsky. The shape of model's skin is changed by macro fiber composite actuators [full video, read more: buff.ly/2NqoVzs]

Discovered Solidworks has a pretty neat rendering capability. here is a rendering of a pitching wing test model I designed a while ago!

Check out our new AIAA technical note where we present a new low turbulence transverse gust system and compare the aerodynamic response of a wing in the new and old gusts. doi.org/10.2514/1.J061…

Girguis and Antonios have a new paper out! "Physics of gust response mitigation in open-loop pitching manoeuvres" cambridge.org/core/journals/…

Tow PIV looks pretty nifty

To celebrate the return of our high speed laser, here is a wing pitching in a gust!

Fully stalled wing encountering a vertical gust. Massive wake, giant vortices, all the good stuff!

At this month's Journal Club at 12pm EDT Friday, July 7, Girguis Sedky et al. will discuss their recent work on effective physics-based control strategies to improve the safety and reliability of flight. See (go.aps.org/3P7IFFL). Register for free at go.aps.org/44sQQ3F.

If you're ever curious about the separated wake behind an airfoil, here is a 1000 fps gif snippet flow visualization in a wind tunnel!

Taking inspiration from bird feathers, Princeton engineers have found that adding rows of flaps to a remote-controlled aircraft’s wings improves flight performance & helps prevent stalling, a condition that can jeopardize a plane’s ability to stay aloft. bit.ly/4ho2ELT
