From: Specific heat capacity of molten salt-based alumina nanofluid
Effects of NP size and concentration on the SHC of the nanofluid. The cross mark at 0 vol.% is the SHC of the molten salt without doping with NPs (measured using model Q20 of TA). The red dash and blue dash-dot lines show the model prediction using Equation 1 for 13- and 90-nm alumina NPs at various volume fractions. The red solid squares and blue open squares are the experimental results of the SHCs of the nanofluids having 13- and 90-nm alumina NPs at 0.9, 2.7, and 4.6 vol.%, respectively. The red solid line and blue dash line are the model predictions considering the nanolayer effect on the SHC of the nanofluid (Equation 5).
