| Abstract: | Ternary molten salts consisting of sodium nitrate,potassium nitrate and sodium nitrite are used as the base material for the graphene nanoplatelets.Different scanning calorimetry is employed to measure the specific heat capacity for both base material and resultant nanofluids.The effect of concentration of nanoparticles on the specific heat capacity of molten nitrate salt-based nanofluids is investigated.The results show that a maximum enhancement of specific heat capacity of 7.5% is found at an optimal concentration of 1% of graphene nanoplatelets. |
