Using phase change material (PCM) to improve the solar energy capacity of glass in solar collectors by enhancing their thermal performance via developed MD approach

Abstract

One of the key ways to improve energy storage performance is to use advanced materials and elements in building coatings. Dense exterior walls with high thermal insulation properties and absorbent and heat-retaining elements can be made by intelligently combining products to store latent heat based on PCMs. In the present study, the thermal behaviour of glass in the presence of PCM (Decane) has been investigated by molecular dynamics simulation. In this paper, the atomic behaviour of the structure is investigated by temperature and density profiles. And the thermal behaviour of the simulated structure is investigated by heat flux and thermal conductivity. The numerical results show that the maximum density and temperature in fluid particles are 0.09643 atom/Å3 and 1067.51 K. The structure's heat flux and thermal conductivity reach 650.27 W/m2 and 0.74 W/m.K, respectively. In general, the use of phase-change materials can prevent energy loss, reduce energy costs, and while changing the phase of materials, quickly has a positive effect on the appearance of the building (as a result of beauty and performance, which are an integral part) Will leave.
