Abstract:
A water-TiO2nanofluid with a weight fraction of 5% and an average particle size of 75 nm is used to investigate the effect of TiO2 nanoparticles on the crystallization and melting behaviors of deionized water by using differential scanning calorimetry(DSC)at four different cooling rates, 3, 5, 7, 9 ℃/min.The DSC experimental results show that the water-TiO2 nanofluid has a lower supercooling degree and a faster crystallization rate than the deionized water.With the increase in the cooling rate, the influence of the TiO2 nanoparticles on the supercooling degree of the deionized water becomes greater, but on the crystallization rate it turns lower.During the melting process, compared with the deionized water, the water-TiO2 nanofluid has a lower melting temperature, a less latent heat and a higher melting rate.
