402 Investigation on influence of surface roughness of cooling surface on ice structure formed by control of initial ice crystal orientation

Abstract

For Japan one of the important problems to solve is power load leveling since the Great East Japan Earthquake in 2011. Thus, in order to promote the issue, use of ice slurry is hopeful. To form ice slurry there is a promising method where ice growing on a cooling solid surface is scraped. However, ice structure strongly affects the scraping force. Therefore, control of the ice structure itself is essential to reduce the scraping force. So authors have investigated ice structure formed by controlling an initial ice crystal orientation. In this paper, influence of the cooling solid surface roughness on ice structure formed after control of the initial crystal orientation is investigated.
