Abstract
Since frosting to a cooling solid surface has caused many serious accidents accompanying economic losses, it is necessary to clarify the mechanism of frosting to the cooling solid surface both scientifically and technologically. Thus, at first clarification of frosting from generation to primary stage of growth is very important. And considering the size of frost crystals in the primary stage, it is essential to investigate frost crystals in micro scale field. In this paper, using a scanning probe microscope (SPM), frost crystal dimensions/structure/distribution and scraping force of forest ciystals were measured by authors' proposed method, varying the cooling solid surface temperatures. And then, the correlation among frost crystal dimensions/structure/distribution and scraping force of forest crystals were clarified.
