Slamming Forces During Water Entry of a Simple Harmonic Oscillator
John T. Antolik, Jesse L. Belden, Nathan B. Speirs +1
When a blunt body impacts an air-water interface, large hydrodynamic forces often arise, a phenomenon many of us have unfortunately experienced in a failed dive or "belly flop." Be…
The water entry surface seal behavior of spheres at intermediate speed regimes
Akihito Kiyama, Rafsan Rabbi, Nathan Speirs +3
This research focuses on the water entry of spheres in the surface seal regime. Herein, surface seal occurs in the wake of a sphere impact with the water surface and is characteriz…
Impact force reduction by consecutive water entry of spheres
Rafsan Rabbi, Nathan Speirs, Akihito Kiyama +2
Free-falling objects impacting onto water pools experience a very high initial impact force, greatest at the moment when breaking through the free surface. Many have intuitively wo…
Reducing water entry impact forces
Nathan B. Speirs, Jesse Belden, Zhao Pan +4
The forces on an object impacting the water are extreme in the early moments of water entry and can cause structural damage to biological and man-made bodies alike. These early-tim…
Water entry of deformable spheres
Randy C. Hurd, Jesse Belden, Michael A. Jandron +3
When a rigid body collides with a liquid surface with sufficient velocity, it creates a splash curtain above the surface and entrains air behind the sphere, creating a cavity below…
3D synthetic aperture PIV measurements from artificial vibrating vocal folds
Jesse Daily, Joey Nielson, Jesse Belden +2
During speech, air from the lungs is forced past the vocal folds which vibrate, producing sound. A pulsatile jet of air is formed downstream of the vibrating folds which interacts…
Holy balls!
Michael Wright, Ken Langley, Jesse Belden +1
We demonstrate the behavior of three balls skipping off of the water surface: a Superball, a racquetball, and a water bouncing ball (Waboba). The three balls have rebound coefficie…
