We are happy to announce that we were published today in Physics of Fluids highlighting our video entitled "Holy balls! Balls that walk on water." We won last years Milton Van Dyke award at the annual American Physical Society Division of Fluid Dynamics Gallery of Fluid Motion and were invited to publish a short article [...]
Today we were published in Experiments in Fluids. Our article entitled "Three Dimensional Bubble Field Resolution Using Synthetic Aperture Imaging: Application to a Plunging Jet" outlines a method for measuring bubble fields in three dimensions. We are grateful to the reviewers for a positive review and the funding agencies that made this work possible. 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. [...]
A hard-boiled egg spinning on a countertop and passing through a puddle of milk draws milk up the side of the egg and then ejects it at the maximum radius. This same phenomenon occurs for any partially submerged spinning object whose radius increases upward from the fluid surface (e.g., [...]
Reporter Jessica Rasmussen for BYUTV highlighted our lab last week! Their piece highlights how we got started, the types of research we do, how we come up with some of our ideas and where we are going. Enjoy. Link.
Today we were highlighted on the BYU homepage with a video made by BYU broadcasting about rock skipping. The video highlights two methods of skipping stones and our recent work with the Waboba-water bouncing ball. The Daily Herald joined us while we were filming at Utah Lake in May. The article by James Roh gives a [...]
When a ball is dropped into a puddle, momentum is exchanged between the impacting ball and the surrounding fluid, decreasing the rebound height. At impact, a radial jet and splash curtain are formed as fluid is instantaneously displaced by the falling ball. During rebound, the splash curtain is drawn in and a column of fluid [...]
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 [...]
Some of our Waboba/Skipping Stone research made its way to the MIT Technology Review and to the New Scientist!
Some of our work on 3D imaging of flames was featured on Science Friday and BYU Radio Below is the video from the Science Friday piece.
