Abstract

In this study, the performances of
the heat transfer fins during the solidification processes of PCM and nano-PCMS(Al₂O₃
- CuO)  were investigated. These two
situations were considered for both with and without fins. Two different heat
transfer 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 transfer
fins were limited due to the overcooling effect of PCMs. The solidification
process of Base-PCM in the heat storage tank ended in 10 minutes, while the
solidification time of the PCM was determined as 11 minutes by using the Fin 1
design. The solidification process in the heat storage tank with nano-PCM (CuO)
was realized in 13 minutes with the Fin 1 design.
