Study of Frost Properties Correlating With Frost Formation Types

Abstract

Frost formation process was studied by photographic observation, and frost formation types were classified into several groups according to their structure in the temperature range of 0 ∼ −25°C. Frost properties, density and effective thermal conductivity, were clarified in connection with the classified frost formation types, and the prediction of the thermal conductivity was performed by the presented structural model of a frost layer.
