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 [...]

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 [...]

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 [...]

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 [...]

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 [...]

Abstract: The water-entry of ballistic projectiles is investigated using high-speed digital imaging to capture the subsurface cavity dynamics. Specially designed 0.22 caliber projectiles are fired into water at shallow angles to the free surface (5º to 15º) at Mach numbers between 0.3 and 1.0. Redesigned projectile tip geometries allowed projectiles to successfully enter the [...]

Abstract: Ocean science and engineering are exciting and active fields industry as well as academia. “Revolutionizing” marine science and technology requires that future generations have access to strong academic programs in ocean science and engineering. Undergraduates pursing degree programs in ocean engineering at the Massachusetts Institute of Technology (MIT) are introduced to a wide [...]
