Abstract: A highly deformable elastic sphere may bounce poorly on land, but it will skip spectacularly on water. Citation and Link: Truscott, T.T., Belden, J. & Hurd, R., “Water-skipping stones and spheres.” Physics Today, 67, 12, 70, DOI: 10.1063/PT.3.2631, December 2014.
Abstract: We present the results of 3D velocity mea- surements of the flow fields around a free-flying painted lady butterfly (Vanessa cardui) and a tethered mechanical flapper using Synthetic Aperture PIV (SAPIV). The velocity fields presented for the free-flying butterfly have limited spatial resolution; however, leading edge vortices (LEV) and trailing edge [...]

Abstract: We present a study of the forces, velocities, and trajectories of slender (length/diameter = 10) axisymmetric projectiles using an embedded inertial measurement unit (IMU). Three nose shapes (cone, ogive, and flat) were used. Projectiles were tested at vertical and oblique impact angles with different surface treatments. The trajectory of a half-hydrophobic [...]
Abstract: The free-surface impact of solid objects has been investigated for well over a century. This canonical problem is influenced by many physical parameters, including projectile geometry, material properties, fluid properties, and impact parameters. Through advances in high-speed imaging and visualization techniques, discoveries about the underlying physics have improved our understanding of [...]
