Sentences with phrase «supercooled water droplets»

One example where modeling the non-classical behavior of water vapor molecules is importan is the ice nucleation on supercooled water droplets.

In the absence of any ice nuclei, the freezing of supercooled water droplets of a few micrometres in radius, in a process called homogeneous ice nucleation, requires temperatures at or lower than − 39 °C (− 38 °F).

Supercooled water droplets can exist naturally in the upper regions of the planet's atmosphere, but physicists still don't know just how cold liquid water can get.

In - flight ice forms at altitudes up to 7300 metres (24,000 feet), when the aircraft's surfaces hit supercooled water droplets suspended in the air.

A team at the University of Nottingham used a simulation that matches experimental and in situ observations to characterize ice on a spectrum between rime ice that forms from water vapor and glaze ice that forms from supercooled water droplets.

In winter the observers didn't use the anemometer, an instrument for measuring wind speed, for fear it would be damaged by the supercooled water droplets that froze to everything, leaving the observatory caked in windblown ice.

Wergin and Erbe have used their low - temperature scanning electron microscope to infer what happens when falling ice crystals run into fogs of supercooled water droplets on their way down, a common occurrence.

Supercooled water droplets in a cloud can remain liquid at temperatures far below freezing, their surface tension preventing solid crystals from forming.

A contact nucleus converts liquid water to ice by touching a supercooled water droplet.

Not exact matches

On page 1589 of this issue, Kim et al. (2) use an evaporative cooling technique to cool micrometer - sized water droplets to deeply supercooled temperatures and provide evidence for the postulated critical point.

Eventually, when a temperature of about -10 °C is reached, the water droplets of the cloud (which are by then supercooled) begin to freeze and become ice crystals.

Clouds that consist of water droplets at temperatures below 0 ° C. are called supercooled clouds, and they are of great importance in the formation of rain.
