We are excited to announce that Dr. Truscott is a 2015 Office of Naval Research Recipient! The award is linked the work entitled Natural swarms and crowds: Observation and Modeling. This grant allows the Splash Lab to do utilize our 3D imaging techniques to unravel behaviors of swarms and swarming behavior of animals and humans. We [...]
We are proud to announce that our work on spinning spheres in a shallow bath has now been published and featured on the cover of Physics of Fluids! When a hard-boiled egg spins through a pool of milk on the kitchen counter, the milk rises up the sides of the egg and droplets are ejected. This [...]
We have been working towards methods of determining the positions of birds in 3D space as they fly using our Synthetic Aperture imaging approach. Pigeons are particularly easy to film because we can trick them into coming in for food, and then scaring them. These preliminary videos help understand the potential this approach may have [...]
We are happy to announce that our 3D flow fields around a flapping toy and moth is now published in Experiments in Fluids. This work demonstrates the marriage of data from our SAPIV system, wherein we combine, force, flow field, and position measurements synchronously. The velocity fields presented for the free flying butterfly have limited [...]
We are pleased to announce another publication in Physics of Fluids entitled "Catastrophic cracking courtesy of quiescent cavitation" in the September issue. We are featured as one of the Gallery of Fluid Motion papers. These short papers highlight the American Physical Society Division of Fluid Dynamics Gallery of Fluid Motion winners from the previous year! [...]
We are pleased to announce that our article "The water entry of slender axisymmetric bodies" was just published in Physics of Fluids!!! Congratulations to Kyle, Stephen and Tadd. This work was really fun and was the first time we utilized an Inertial Measurement Unit synchronized with our imaging data. The IMU was developed by Stephen [...]
In 2013 at the American Physical Society Division of Fluid Dynamics meeting (APS DFD) in Pittsburg, PA we presented several talks, posters and videos. Each of the titles is listed below along with a short abstract of each one. Pop up height of buoyant rising spheres Tadd Truscott & Randy Munns We examine the [...]
As a moth flaps its wings, a vortex is generated on the leading edge of the wing. The flapping motion allows the vortex to remain attached and provide a lifting force. It is thought that the lifting force from the vortex is what allows moths and other animals with flapping wings to fly and hover. [...]
When a buoyant rising sphere exits the free surface there are several angles of trajectory and heights observed. Children experience this when playing with a ball while swimming. The pop up height and direction of trajectory above the free surface are dependent on the release depth of the sphere below the free surface. The release [...]
Previous studies have shown that applying a hydrophobic coating to one-half of a hydrophilic sphere will cause asymmetric cavity formation and a deflection in the trajectory of a sphere. Half of an axisymmetric projectile will be coated with the hydrophobic coating and dropped in a similar manner to determine if there is similar asymmetric cavity [...]
