Adding a New Dimension to a Traditional Conduction Lab

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 [...]

Error Propagation Dynamics of PIV-based Pressure Field Calculations

Abstract: After more than 20 years of development, PIV has become a standard non-invasive velocity field measurement technique [1], and promises to make PIV-based pressure calculations possible [2]. 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 [...]

Advances in Light Field Imaging for Measurement of Fluid Mechanical Systems

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 [...]

Light field measurement of reflective interfaces

Abstract: The geometric reconstruction of a diffuse surface can be accomplished with a simple projector-camera system [1]. 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 [...]

APS 2016 Participation

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 [...]

Water exit dynamics of buoyant spheres, 2016

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 [...]
