These twosituations were considered for both with and without fins. Two different heattransfer fins were considered in the study.The investigation was carried out using both experimental (for Base-PCM)and numerical methods. The results showed that the effects of heat transferfins were limited due to the overcooling effect of PCMs. The solidificationprocess of Base-PCM in the heat storage tank ended in 10 minutes, while thesolidification time of the PCM was determined as 11 minutes by using the Fin 1design. The solidification process in the heat storage tank with nano-PCM (CuO)was realized in 13 minutes with the Fin 1 design.
