Entropic Aspects of Supercooled Droplet Freezing*
نویسنده
چکیده
We estimate a lower bound on the amount of latent heat liberated by freezing droplets. Based on a physical picture of the freezing process, we arrive at an estimate for the effective latent heat (calculated along a reversible path), suitable for heat budget calculations of glaciating clouds. In addition, we arrive at a quadratic dependence on supercooling for the irreversible contribution to heat exchange during the freezing process. The proportionality factor is estimated as -0.3 J mol-1 K-2.

Controlling condensation and frost growth with chemical micropatterns
In-plane frost growth on chilled hydrophobic surfaces is an inter-droplet phenomenon, where frozen droplets harvest water from neighboring supercooled liquid droplets to grow ice bridges that propagate across the surface in a chain reaction. To date, no surface has been able to passively prevent the in-plane growth of ice bridges across the population of supercooled condensate. Here, we demonst...
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...
متن کاملSupercooled Water Droplet Impacting Superhydrophobic Surfaces in the Presence of Cold Air Flow
In the present work, an investigation of stagnation flow imposed on a supercooled water drop in cold environmental conditions was carried out at various air velocities ranging from 0 (i.e., still air) to 10 m/s along with temperature spanning from −10 to −30 ◦C. The net effect of air flow on the impacting water droplet was investigated by controlling the droplet impact velocity to make it simil...
متن کاملThe Effect of Freezing Drizzle, Sleet and Snow on Microphysical Characteristics of Supercooled Fog during the Icing Process in a Mountainous Area
Both the similar and different effects of freezing drizzle, sleet and snow on microphysical properties of supercooled fog were analyzed for fourteen events during a comprehensive wire icing, fog, and precipitation observation experiment conducted at Enshi radar station (30◦17′N, 109◦16′E; 1722 m a.s.l.) on a hilltop in Shibanling, Hubei, China. Liquid precipitation is in a relatively stable for...
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...
