Citation: Mach stem formation during outdoor acoustic shock propagation is investigated using spherical oxyacetylene balloons exploded above pavement. The location of the transition point from regular to irregular reflection and the path of the triple point are experimentally resolved using microphone arrays and a high-speed camera. The transition point falls between recent analytical [...]

We are pleased to announce the publication of a paper in Measurement Science and Technology entitled "Error propagation dynamics of PIV-based pressure field calculations: How well does the pressure Poisson solver perform inherently?" In the article we use mathematics to explain why and how the Poisson equation increases errors from PIV data. The abstract is below and the [...]
In June 2016 we had a paper published in Nature Plants entitled "The upside-down water collection system of Syntrichia caninervis." This paper focuses on the this desert moss collects water from the air using specially shaped a hair (awn) at the end of each leaf to collect water from dew, fog, or humid atmospheres. Our [...]
We are pleased to announce the publications of our article "Crown sealing and buckling instability during water entry of spheres" in the Journal of Fluid Mechanics in May 2016. The abstract is below and the full article can be found here. Abstract: We present new observations from an experimental investigation of the classical problem of [...]
In May of 2016 we had an article published in Experiments in Fluids entitled "The effect of ambient pressure on ejecta sheets from free-surface ablation." The full article can be found here, and the abstract is below. Abstract: We present observations from an experimental study of the ablation of a free liquid surface promoted by a [...]
This week the 3rd annual Utah Underwater Robotics competition at the Lehi Legacy center. Over 175 teams of middle and elementary school-age students participated. ROV kits were given to the students at the start of the year and they used their knowledge to build small remotely operated underwater vehicles (ROVs). The year-long program and competition was a great [...]
We are proud to announce that we were published in Nature Communications in February for our work on skipping spheres. Our article called "Elastic Spheres Can Walk on Water" further clarifies understanding the interaction of fluid-elastic bodies during water impact. Here is the link to the full article, the abstract is below Abstract: Incited by [...]
As a follow up to our work on reducing urinal backsplash at APS in 2013, Splash Lab PhD student Randy Hurd has developed a urine black hole which prevents urine from splashing back. At APS in 2015 Hurd explained that the inspiration for the black hole came from the moss Syntrichia caninervis, which is a super absorbent [...]
