Abstract：

In　order　to　enhance　specific　heat　capacity　of　the　low　melting　point　salt　(Ca(NO3)2-KNO3-NaNO3-LiNO3),　low　melting　point　salt　(LMPS)　nanofluid　was　prepared　by　adding　SiO2　nanoparticles　with　size　of　20　nm　into　the　low　melting　point　salt　with　using　ultra-sonication.　The　influence　of　nanoparticles　dispersion　on　enhancing　specific　heat　of　the　low　melting　point　salt　was　investigated　by　experiments.　Two　factors　of　ultra-sonication　(time　for　sonication　and　frequency)　were　researched.　The　specific　heat　capacity　was　measured　by　using　a　differential　scanning　Calorimetry　(DSC),　and　the　microstructures　following　solidification　was　observed　by　using　a　scanning　electron　microscope　(SEM).　Results　show　that　the　specific　heat　of　the　LMPS　nanofluid　is　significantly　improved,　when　nanoparticles　disperse　evenly　in　the　LMPS　nanofluid.　The　average　specific　heat　of　the　LMPS　nanofluid　is　1.868　J/(g·K)　and　the　enhancement　of　the　specific　heat　is　14%~22%　in　200~350℃.　Moreover,　it　is　verified　the　fact　that　the　ultra-sonication　is　a　stable　method　of　preparing　LMPS　nanofluid.　©　2016,　Editorial　Department　of　Journal　of　Beijing　University　of　Technology.　All　right　reserved.
