Abstract: We present an integrated experimental and numerical two-dimensional heat conduction exercise to provide analytical and visual validation of basic concepts. The advanced nature of heat transfer leads many instructors to spend a considerable time on numerical techniques. However, due to time limitations, these numerical approaches are often only applied to highly simplified problems within [...]
Abstract: After more than 20 years of development, PIV has become a standard non-invasive velocity field measurement technique , and promises to make PIV-based pressure calculations possible . However, there are always uncertainties in PIV velocity fields, and these uncertainties will eventuality propagate through integration and contaminate the pressure field. Some researchers have noticed this [...]
Abstract: Modeling of fluid mechanical systems benefits from and often requires high-fidelity three-dimensional data. This need has pushed experimental fluid dynamicists to look to other fields, such as computational imaging, for innovative measurement methods. Light field (LF) imaging is one (broad) method that has found traction in experimental fluids, mostly being used for three-dimensional velocity [...]
Abstract: The geometric reconstruction of a diffuse surface can be accomplished with a simple projector-camera system . However, in the case of specular objects - such as a gas-liquid interface (GLI) - these same methods fail to uniquely define surface location and orientation. Several methods have been demonstrated for recovering specular surface geometry including: using [...]
A remotely operated vehicle scaffolded actibity is increading student and teacher interest in STEM – a reporting on a three-year study funded by the Office of Navel Research
Abstract: A Remotely Operated Vehicle Scaffolded Activity is Increasing Student and Teacher Interest in STEM – a Reporting on a Three-‐year Study Funded by the Office of Naval Research For the past three years a university in the western United States has worked to build a scaffolded activity, using curriculum from STEM [...]
This week our article "The upside-down water collection system of Syntrichia caninervis" was featured as one of Nature Plants most popular articles published in 2016! We are excited to hear this news and are proud of the hard work that was put into this publication. The announcement and other featured articles can be found here.
At APS 2016 in Portland, Oregon we were happy to submit several talks, posters, and videos. The titles and short abstracts for each one are listed below. We had an amazing time at APS and are very proud of the incredible work our students accomplished last semester. Bird beaks bear the brunt of bashing impact [...]
This year at APS DFD 2016, our video entitled "The Shear Joy of Watching Paint Dry" was awarded the Milton van Dyke award! We are honored to have received this award and are proud of all the hard work our students put into making the video. Watch the video below, enjoy!
Abstract: Buoyant spheres released below the free surface can rise well above the surface in a phenomenon known as pop-up. Contrary to intuition, increasing the release depth sometimes results in a lower pop-up height. We present the pop-up height of rising buoyant spheres over a range of release depths (1–12.5 diameters) and Reynolds numbers (4×104 [...]
We are excited to report the publication of our article "Water exit dynamics of buoyant spheres" in the Physical Review Fluids. The full article can be found here and the abstract is below. Buoyant spheres released below the free surface can rise well above the surface in a phenomenon known as pop-up. Contrary to intuition, [...]
