چکیده

Abstract The thermal properties of Octadecane vary due to the addition copper oxide (CuO) nanoparticles. synthesis two nano‐enhanced phase change material (NEPCM) required implementation two‐step method, using as base and CuO nanoparticles at 2.5 5.0 wt%. experimental characterization determined specific heat capacity, conductivity NEPCMs solid phase, including enthalpy temperature. These results were then utilized for computational simulation charging (solidification) discharging (melting) processes within a spherical enclosure, employing ANSYS/Fluent software. incorporation led an increase in while causing decrease enthalpy, temperature Octadecane. revealed reduction melting period improvement solidification both NEPCMs. In terms melting, convective transfer coefficient increased by approximately 27.4% 3.2% NEPCM wt% CuO, respectively. During process, overall experienced significant 43.8% 59.8% wt%,

Solidfication of Phase Change Materials Encapsulated in Vertical Tubes

Solidification of phase change materials encapsulated in a vertical shell which contains also the heat transfer fluid tubes is studied using a fixed grid numerical model. The solution of the system consists of adopting a velocity field of a complete developed flow coupled with the energy equations of the heat transfer fluid (HTF), the pipe wall and the phase change material (PCM). The control v...
