Abstract Detailed numerical analysis is presented for heat transfer characteristics of charging or discharging process in phase change thermal energy storage
unit with inner corrugated tube. The results indicated that the charging or discharging rate of phase change material (PCM) for the case of inner
corrugated tube is obviously higher than that in unit with inner plain tube due to the increasing heat transfer surface. The heat transfer rate increase
with the increasing mass flow rate. However, when the mass flow rate of heat transfer fluid (HTF) is greater than 0.0315kg/s, the charge and
discharge time can not be obviously shorten… More >
