Abstract
Adhesion of frost crystals to a cooling solid surface has caused many serious accidents accompanying economic losses. Thus, it is necessary to clarify the mechanism of frost crystal adhesion to the cooling solid surface both scientifically and technologically. Considering the size of frost crystals, it is essential to investigate frost crystals in nano-micro scale fields. Thus, authors have developed the methods for measuring frost crystal dimensions/structure and scraping force of forest crystals from the cooling solid surface by using a scanning probe microscope (SPM). And, the methods' validity and effectiveness have been clarified. In this paper, a new method to estimate distribution of frost crystals is also proposed, and the correlations among frost crystal dimensions/structure, distribution of frost crystals and scraping force of forest crystals were clarified.
