Congratulations to Hamid on accepting a faculty position at Lawrence Tech. in Michigan. Hamid will start there in August.
Welcome to our iTeam members: Zach, Diana, Molly, Maddie, Ian and KJ, who are joining the lab for the summer to work on bat flight and bio-inspired robotics.
nice video piece by Voice of America on our tidal energy harvesting project and our presentation at the ARPAe Summit in Washington DC
Congratulations to Daegyoum (Kim) and Ben (Strom) – their paper on Tidal Energy Harvesting (with Shreyas Mandre and myself) Harvesting has finally appeared in press after long delays.
Congratulations to Jillian, Michael and David’s on the publication of their paper in Applied Physics Letters on electro-active membrane modelling
No – thats not Kenny, thats Jonah Hill and Miles Teller, admiring a pair of Rousettus bats. Kenny and his collaborator, Soon-Jo Chung (of Caltech) were in Spain, appearing on the Spanish variety show – El hormiguero (“the anthill”) talking about our collaborative NSF project on bat flight and bio-inspired robotic bats. Oh yeah, Jonah Hill and Miles Teller were there too!
Congratulations to: Cosima Schunk, who defended her PhD in May and is off to Colorado for a Post Doc with Sean Humbert; to Kyohei Onoue, who also defended his PhD in May and is staying at Brown as a Post Doc; to Joon Park who defended his PhD in August and is off to Minnesota for a Post Doc with Satish Kumar – Farewell, and Bon Voyage to all!
Benvenuto to Matteo di Luca who joined the lab from Italy as a new PhD student!
Congratulations to Kyohei and Cosima who received their PhDs yesterday! Cosima is moving on to a Post Doc at the University of Colorado and Kyohei is continuing on as a Post Doc here at Brown!
Congratulations as well to Nguyen Le, Liza Gibbs and Hayley McClintock, who received their Batchelor’s degrees. All the best to you in your endeavors beyond College Hill!
We report on the dynamics of the formation and growth of the leading-edge vortex and the corresponding unsteady aerodynamic torque induced by large-scale flow-induced oscillations of an elastically mounted flat plate. All experiments are performed using a high-bandwidth cyber-physical system, which enables the user to access a wide range of structural dynamics using a feedback control system. A series of two-dimensional particle image velocimetry measurements are carried out to characterize the behaviour of the separated flow structures and its relation to the plate kinematics and unsteady aerodynamic torque generation. By modulating the structural properties of the cyber-physical system, we systematically analyse the formation, strength and separation of the leading-edge vortex, and the dependence on kinematic parameters. We demonstrate that the leading-edge vortex growth and strength scale with the characteristic feeding shear-layer velocity and that a potential flow model using the measured vortex circulation and position can, when coupled with the steady moment of the flat plate, accurately predict the net aerodynamic torque on the plate. Connections to previous results on optimal vortex formation time are also discussed.
