Frost Growth Characteristics on Silver Iodide (AgI) and Platinum (Pt) Stripe-Patterned Surfaces

Abstract

This research investigates frost growth characteristics on silver iodide (AgI) and platinum (Pt) stripe patterned surfaces, fabricated using UV-lithography, under desublimation and condensation frosting conditions. Different frost growth behaviors were observed between AgI and Pt patterns, i.e. horizontal frost with dendrite-shaped ice crystals grew on the AgI stripes, and a combined frost growth of dendritic horizontal growth at the stripe edges and random growth at the top were observed for the Pt stripes. This study provides new insights into the influences of ice nucleation agents such as AgI for controlling the frost height and density.
