The present paper describes experimental and computer simulation results for horizontal U-tube latent thermal storage units with a eutectic of sodium hydroxide-sodium nitrate. Through 1000 melting-freezing (charge-discharge) cycle tests on two 30 kWh scale storage units of bare-tube and finned-tube stypes, the heat transfer characteristics were evaluated. Computer simulations of both types of storage units were performed with a two dimensional model. For the finned-tube type, the effect of fin was included in the effective thermal conductivity of molten salt around the tubes. The calculated results were in good agreement with experimental ones. The heat transfer characteristics were evaluated for various storage units with different parameters such as number of passes, and number of heat transfer pipes.
