Universality of tip singularity formation in freezing water drops.
A drop of water deposited on a cold plate freezes into an ice drop with a pointy tip. While this phenomenon clearly finds its origin in the expansion of water upon freezing, a quantitative description of the tip singularity has remained elusive. Here we demonstrate how the geometry of the freezing front, determined by heat transfer considerations, is crucial for the tip formation. We perform sy...
متن کاملGlue drops inside hadrons
We present experimental evidences for the existence of a semi-hard scale in light hadrons. This includes the suppression of gluon radiation that is seen in high mass hadron diffraction; the weak energy dependence of hadronic total cross sections; the small value of the Pomeron trajectory slope measured in photoproduction of J/Ψ; the weakness of gluon shadowing in nuclei; shortage of gluons in t...
متن کاملImmersion freezing of supercooled water drops containing glassy volcanic ash particles
The freezing temperatures of hundreds of water drops with radii 20–50 lm containing known average concentrations of suspended, mostly micronto submicron-sized, volcanic ash particles composed of SiO2-rich glass were recorded using optical microscopy. As expected, the ash suppresses supercooling, and in contrast to earlier studies of much larger ash particles, the median freezing temperature cle...
متن کاملEvaporation freezing by contact nucleation inside-out
[1] Ice formation in atmospheric clouds is crucial to our understanding of precipitation and cloud radiative properties. In recent work it was shown that heterogeneous ice nucleation rates can be strongly enhanced by a form of surface crystallization (Shaw et al., 2005). Here we present new laboratory data and consider the implications for contact nucleation and its relevance to ice nucleation ...
متن کاملWater Drops on Surfaces
Water motion is a highly complex phenomenon. From ocean waves to raindrops, water is described by a wide range of shapes and is affected by a wide range of forces. This paper presents a physically-based method of modeling the latter phenomenon raindrops. This model can handle bodies of water with varying underlying terrain, as well as many different fluids, but cannot represent spray systems, w...
