Numerical simulation of nucleation phenomena during
crystallization demands a definition several parameters of the clusters of
crystalline molecules in initial amorphous phase. Among of such key parameters
are a numbers of molecules on the surface of cluster these can be transformed
from one phase to other changing number of molecules in the cluster.
Letís cluster has i molecules with volume vm
Effective size of d is defined by equation vm =
The volume of the cl...
A phenomena of spontaneous appearance of crystal phase inside of liquid and then
self sustained growth up to the point of
complete transformation of liquid into crystal is the very commonly observed for producing ice in
refrigerator and most paradoxical from point of clear demonstration of
limitations of direct application of thermodynamic laws in case when macro
effects are seed out from micro scale incident when statistical fluctuations
play major role.
The paradox of nucleation...
