Figure 3

Variation of k/kf and percentage enhancement in thermal conductivity, as a function of temperature, for the PCM loaded with various concentrations of (a) CBNP, (b) NiNP, (c) CuNP, (d) AgNW, (e) MWCNT, and (f) GNP nanoinclusions. For comparison, the variation of k/kf in the case of PCM, without any nanoinclusions, is also shown in the figures. The variation of k/kf can be divided into three regions, viz., region-I (liquid state), region-II (phase transition), and region-III (solid state).
