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.

使用相变材料 (PCM) 通过开发的 MD 方法提高玻璃的热性能,从而提高太阳能集热器中玻璃的太阳能容量

提高储能性能的关键方法之一是在建筑涂料中使用先进的材料和元素。可以通过智能组合产品来制造具有高隔热性能的致密外墙以及吸收和保温元件,以存储基于 PCM 的潜热。在本研究中,通过分子动力学模拟研究了在 PCM(癸烷)存在下玻璃的热行为。在本文中,该结构的原子行为通过温度和密度分布进行了研究。并通过热通量和热导率研究模拟结构的热行为。数值结果表明流体粒子中的最大密度和温度为0.09643 atom/Å 3和1067.51 K。结构的热通量和热导率分别达到650.27 W/m 2和0.74 W/mK。一般来说,使用相变材料可以防止能量损失,降低能源成本,在改变材料相的同时,迅速对建筑物的外观产生积极影响(由于美观和性能,这是一个不可分割的部分)将离开。
