Abstract
In the present study, systems efficiency, heat transfer rate, exergy destruction, entropy generation number, exergetic efficiency, liquid fraction, and solidification temperature contours are determined for double-tube thermal energy storage (DT-TES) and triple-tube thermal energy storage (TT-TES) systems using MXene-based nano-enhanced phase changes material (NEPCM). The findings showed that the DT-TES using pure beeswax PCM in pure solidification has a discharge exergy 14.76% lower than that of MXene-based NEPCM. Using the TT-TES system, pure PCM and MXene NEPCM produced 2.47% and 3.62% less entropy at 2400 s than pure beeswax. Over 2400 s, DT-TES using pure beeswax discharged more effectively. Because of the superior thermophysical characteristics of MXene nanoparticles, the TT-TES system solidified beeswax PCM 18.53% faster than pure PCM. Consequently, under TT-TES latent heat, MXene-based nano-enhanced beeswax PCM solidifies more quickly per volume.
