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.
