DETERMINING EFFECTS OF HEAT TRANSFER FINS ON THE SOLIDIFICATION PROCESS OF PCM AND NANO-PCM WITH A RECTANGULAR COOLER

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.
