Freezing, fragmentation, and charge separation in sonic sprayed water droplets
Water droplets are generated by sonic spray, transferred into vacuum through a capillary interface, and then passed through two image charge detectors separated by a drift region. The image charge detectors measure the charge and velocity of each droplet. For around 1% of the droplets, the charge changes significantly between the detectors. In some cases it increases, in others it decreases, an...
متن کاملHeterogeneous freezing of water droplets containing kaolinite particles
Clouds composed of both ice particles and supercooled liquid water droplets exist at temperatures above ∼236 K. These mixed phase clouds, which strongly impact climate, are very sensitive to the presence of solid particles that can catalyse freezing. In this paper we describe experiments to determine the conditions at which the clay mineral kaolinite nucleates ice when immersed within water dro...
متن کاملSize dependence of volume and surface nucleation rates for homogeneous freezing of supercooled water droplets
The relative roles of volume and surface nucleation were investigated for the homogeneous freezing of pure water droplets. Experiments were carried out in a cryogenic laminar aerosol flow tube using supercooled water aerosols with maximum volume densities at radii between 1 and 3 μm. Temperatureand size-dependent values of volumeand surface-based homogeneous nucleation rates between 234.8 and 2...
متن کامل\Sprinkling With Water Protects Hardwood Logs In Storage
In a study at Helena; Arkansas, sprinkling hardwood logs during summer storage greatly reduced degrade caused by stain and insects. Logs of four Southern species were stored for 16 weeks starting July 18, 1962. The study was conducted cooperatively by the Southern Hardwoods Laboratory and the Chicago Mill and Lumber Company. While Western softwood and Northern hardwood mills have been using thi...
متن کاملCritical Radius of Supercooled Water Droplets: On the Transition toward Dendritic Freezing.
The freezing of freely suspended supercooled water droplets with a diameter of bigger than a few micrometers splits into two rather different freezing stages. Within the first very fast dendritic freezing stage a spongy network ice with an ice portion of less than one-third forms and more than two-thirds of liquid water remain. In the present work the distribution of the ice portion in the drop...
