| Abstract | Carbon nanotubes (CNTs) are one of the most promising discoveries in modern science. Since its discovery in 1991, CNTs have captured a great deal of attention worldwide because of their exceptional mechanical, electrical and thermal properties. CNTs have emerged as a potentially effective reinforcing material in improving mechanical and thermal capabilities of phase change materials (PCMs). Capric acid as PCMs draws much interest to scientists because of its heat storage capacity, accessibility, cost-effectiveness, and low reactivity. However, their properties remain to be below average if no enhancing elements are added. In this study, the mechanical and thermal properties were examined with varying parameters such as packing density, CNT type, and length-over-diameter (L/D) ratio. By virtue of molecular dynamics simulation, a dense amorphous cell was created using the Forcite module of BIOVIA Material Studio software and simulations were performed. The CA packing density increases both its mechanical properties and thermal conductivity while CNT type did not reveal any effect on them. Whereas the mechanical properties (except elastic modulus) and thermal conductivity increase with L/D ratio. The amorphous cells were subjected to different temperature and pressure using the dynamics task of Forcite and results showed that temperature had no influence on thermal conductivity when the PCM is in a solid state, and had a decreasing trend in a liquid state. No trend was found with the effect of pressure. The latent heat of fusion of the PCM was found to be 333.65 kJ/mol, a ten-fold increase of that of pure CA. |
