A simulation of the thermal storage performance of the metal fin embedded concrete

The primary aim of the present study was to evaluate thermal storage performance of the storage medium embedded with metal fins and to prepare and accumulate design data. Thus, basic study was performed on concrete structure embedded with metal fins by means of model experiment and numerical analysis.

As the measurement, it was confirmed that thermal storage time was reduced and storage efficiency was improved due to the embedding of metal fins. Forthermore, Numerical analysis was carried out by using number of fins, embedding depth, and materials of fins as parameters, and general guidelines for the working design were determined.
