Microscopic study of frost inception.

Author(s) : GEORGIADIS J. G.

Summary

Under a wide range of natural and forced convection conditions over horizontal flat surfaces, the phenomenon involves, first, the formation of supercooled water droplets, second, their sudden nucleation (onset of freezing), and third, ice crystal growth. In an attempt to understand the behaviour of frost, morphological information is needed on a microscopic level. The authors report a high-resolution, video rate (30 frames per second) visualization of frost forming on horizontal substrates exposed to humid air. Such studies bolster our understanding of several fundamental frost phenomena (during its early growth stage), such as the growth of ice crystals and their interaction with subcooled droplets.
