A Preliminary Study of Ice Grown by Droplet Accretion Using Water-Insoluble Particles as Tracer

Abstract

The migration of water-insoluble particles during freezing was used to study the structure of ice grown by droplet accretion. Experiments were performed in a cold tunnel under different growth conditions using nickel powder as a tracer; the resulting deposit was examined using the x-ray microradiograph technique. Analysis of the types of tracer particle aggregates provided a description of the freezing processes. It was concluded that this method could be used as an additional tool in studies of the various ice growth conditions found in nature.
