Heat transfer enhancement of ice storage systems: a systematic
Abstract Thermal resistance of ice slows down the charging/discharging process of ice storage systems which results in long operating cycles and thus high energy consumption. To overcome this drawback, various heat transfer enhancement methods have been investigated in the literature. In this paper, a systematic review of
