Fig. 12.5 Temperature field under thermal charging mode as a function of time for two different
concentrations of nanoparticles a pure paraffin wax, b NPs with concentration 0.05%, and c NPs
with concentration 0.4%
curves for various nanoparticle laden PCMs in case of surface heating (see Fig. 12.5).
Finally, thermal images of various samples both under optical charging as well thermal charging modes have been captured (see Fig. 12.6) using IR camera (Keysight
U5855A TrueIR thermal imager).
