Abstract Phase change materials are highly effective in improving the thermal efficiency of a heat exchanger, making them choice for enhancing renewable energy to achieve feasible environment. In this study, myristic acid (MA) was used as phase material and aluminium oxide (Al 2 O 3 ), copper (CuO) 2.5, 5, 10 wt % multi-walled carbon nanotubes (MWCNT) 1.0, 1.5, were nanoparticles produce MA-embedded nanocomposite (NCPCM). The characterization studies, namely x-ray diffraction, Thermal Conductivity, field emission scanning electron microscope (FESEM), Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy, Differential Scanning Calorimetry (DSC) Thermogravimetric analysis (TGA) performed on ensure their homogeneous distribution property enhancement fabricated samples. addition, Computational Fluid Dynamics (CFD) conducted assess impact NCPCM rates solidification melting. microscopy confirms micro/nanoparticles Al , CuO, MWCNT with MA. From diffraction (XRD) analysis, nature NCPCMs identified. (FTIR) Spectroscopy results confirmed absence new particle formation due physical interaction between nanocomposites acid. samples undergone 500 cycles reliability. It is evident from test that addition base PCM enhances properties. performance wt% MWCNT-embedded MA superior oxide. DSC revealed added possessed highest variation 8.6% its latent storage value compared pure had significant other compositions. Adding has increased conductivity 0.15 W mK −1 0.38 .
