Numerical analysis is being conducted to investigate the effect of Nano fluids on the melting process of phase change materials (PCMs) in a semi-cylindrical container.

Analytical investigation of the impact of Nano fluids on the melting process of phase change materials (PCM) inside a semi-cylindrical container. In order to analyse the study in a quantitative manner, the combination of enthalpy and porosity was used using the ANSYS/FLUENT 22 programme. This experiment used phase transition materials, namely paraffin wax (RT58). Based on the findings of this research, it is seen that the inclusion of Nano fluid in the PCMs accelerates the dissolving process compared to the PCMs without these materials. The use of nanomaterials results in a reduction in the time needed to complete the melting process by 3 %, 4 %, and 5 % when used at concentrations of 10 %, 20 %, and 30 %, respectively. This study is important for the use of phase-change materials in the cooling of large electronic devices.
