M.M. Kenisarin, et al. Journal of Energy Storage 27 (2020) 101082 Fig. 43. Typical results obtained by Chandrasekaran et al.: a – solidified mass fraction vs time for tbath = =-2 °C [106]; b – solidified mass fraction vs time for tbath = =-6 °C [107]; c – variation of solidification duration for various volume fills for tbath = =-12 °C [108]; d – variation of solidification duration with solidified PCM mass for tbath = =-6 °C [109].

Five resistance thermometers were installed to monitor the temperature inside the spherical shell. The solidified mass fraction was determined at the bath temperatures of – 6 and – 2 °C. The typical experimental result is shown in Fig. 43a. The solidification process of water/multiwall carbon nanotubes (MWCNT) composition was investigated in [107]. The deionized water as PCM, sodium dodecyl benzene sulphonate (SDBS) as a surfactant, Pseudo- monas as a nucleating agent and MWCNT as a nanomaterial were used for the preparation of the composite PCM. All additive components had 0.1 wt.%. The typical data obtained is shown in Fig. 43b. The ther- mophysical properties were not measured. In [108], solidification characteristics of water, as the PCM, were investigated to define the effect of volume filled by the PCM in a spherical capsule.
