Elena Ionela CHERECHES, Marius Ionut CHERECHES, Alina Adriana MINEA

Abstract


The idea of adding nanoparticles to classical heat transfer fluids is a hot research topic, while it is interesting and stimulating, especially through the use of non-conventional fluids, such as polyethylene glycol (PEG). In this research, the specific heat capacity of PEG 400 and MWCNT nanoenhanced PEG 400 fluids was experimentally studied at ambient temperature and with temperature variation in the range of 293.15 and 333.15 K. The specific heat capacity of the samples increased with the temperature and the addition of MWCNT nanoparticles definitely influences this property. The experimental results were also compared with theoretical correlations. In conclusion, the studies on these new fluids are still in their pioneering zone and the experimental effort needs to be intensified.
