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 [...]
Error propagation dynamics of PIV-based pressure field calculations: How well does the pressure Poisson solver perform inherently?, 2016
Abstract: Obtaining pressure field data from particle image velocimetry (PIV) is an attractive technique in fluid dynamics due to its noninvasive nature. The application of this technique generally involves integrating the pressure gradient [...]
The upside-down water collection system of Syntrichia caninervis, 2016
