Stable-streamlined and helical cavities following the impact of Leidenfrost spheres: Publication in Journal of Fluid Mechanics

In November, our collaborators and we published the article “Stable-streamlined and helical cavities following the impact of Leidenfrost spheres” in the Journal of Fluid Mechanics. The abstract is below and the full article can be found here. Enjoy! We report results from an experimental study on the formation of stable–streamlined and helical cavity wakes following the free-surface [...]

Error sources and propagation in three-dimensional microscopic light field particle image velocimetry.

Abstract: Three-dimensional (3D) microscopic velocimetry methods have been increasingly developed in recent years to meet the measurement demands of microfluidic systems. As all 3D microscopic velocimetry techniques involve reconstructing a volume from two-dimensional (2D) sensor(s), sources of uncertainty arise that are unique from 2D velocimetry methods. This study discusses the error sources associated with a [...]

Advances in Light Field Imaging for Measurement of Fluid Mechanical Systems.

Abstract: Light field imaging is becoming an increasingly useful tool for measuring fluid mechanical systems. We present advances in light field imaging for fluids along three directions. The first concerns robust reconstruction of fluid measurement volumes using synthetic aperture refocusing followed by deconvolution. Then, we discuss how a flame, which distorts the refractive index, augments [...]

Modeling of Hyperelastic Water-Skipping Spheres using Abaqus/Explicit.

Abstract: This research seeks to model and elucidate the physics of water impact of elastomeric spheres, including the mechanisms by which severe deformations enable spheres to skip off the free water surface. The interplay between solid mechanics and fluid mechanics, or fluid-structure interaction, is extremely rich and complicated for this physical phenomenon. This research [...]

Simultaneous tracking of vocal fold superior surface motion and glottal jet dynamics.

Abstract: Synthetic aperture particle image velocimetry is used with an excised human vocal fold model to study the airflow between the vocal folds during voice production. A whole field, time-resolved, 3D description of the flow is presented over multiple cycles of vocal fold oscillations. The 3D flow data are synchronized with a 3D reconstruction [...]

Whole-Field 3D Characterization of a Pulsating Jet Using Synthetic Aperture Particle Image Velocimetry

Abstract: In this study synthetic aperture particle image velocimetry is used on an excised human vocal fold model to study the airflow over the vocal folds during voice production. For the first time, a whole-field, time-resolved, 3D description of the flow is presented over one cycle of vocal fold oscillation. Complex, unsteady, 3D flow [...]

Physics of Elastic Spheres Skipping on Water

Abstract: It is well known that one can skip a stone across the water surface, but less well known that a ball can also be skipped on water. The Waboba® is an elastic ball used in a game of aquatic keep away in which players pass the ball by skipping it along the water. We [...]

Three-dimensional synthetic aperture imaging and resolution of multi-phase flows

Abstract: Three-dimensional multiphase fluid flows demand advanced and innovative measurement systems in order to fully resolve the flow physics. Dense bubbly multiphase flows cannot be readily imaged by traditional, non-invasive flow measurement techniques due to the bubbles occluding optical access to the interior regions of the volume of interest. We present a novel technique [...]

Evaluating derivatives of experimental data using smoothing splines

Abstract: Instantaneous derivatives of high-precision experimental data can be evaluated by fitting the data with a smoothing spline. This paper presents a novel and robust method for choosing the best spline fit and, hence, the best prediction of the derivatives. Typically, a smoothing spline is fit by choosing the value of a smoothing parameter that [...]
