Abstract

We report the results of experiments using high resolution imaging of transient frost melting to obtain quantitative information on frost thickness and porosity. A highly controlled test chamber and surface are described along with visual and digital methods extract quantitative data. When the frost layer approaches the fully permeated state and melting proceeds to liquid droplets, we report a digital method for analysis of droplet size and geometry. For each of the measurements, an error analysis is presented. We find that the measurement techniques employed in the present study provide faster data acquisition and higher accuracy than traditional approaches. The present data are utilized successfully in a companion paper in connection with an empirically based model of frost growth.
