G135 初期氷結晶の方向制御と生成氷構造の相関に基づくかき取り力の抑制に関する検討(OS-14: 固液相変化問題)

Abstract

As one of typical formation methods of ice slurry, there is a harvest method where ice growing on a cooling solid surface is scraped by a scraper. This method has a merit that consideration of ice adhesion to the cooling solid surface is not required. However, it can be supposed that a scraping force of the formed ice depends on ice structure strongly. In this paper, the correlations among the controlled initial crystal orientation, initial freezing layer and ice structure were clarified, and then, apossibility of control of the scraping force was also clarified based on the correlations.
