Abstract
Cryogen Spray Cooling (CSC) is an auxiliary procedure that pre-cools the epidermis during Laser Derma-
tologic Surgery (LDS) to avoid non-specific epidermal thermal damage. During CSC, explosive atomization, in-
flight evaporation and droplet-substrate interaction affect heat extraction from the substrate. In order to understand
the heat transfer mechanism of this complex process, we first study the heat transfer between a single cryogen
