向异性热导率对相变储能墙体传热特性的影响
Influence of anisotropic thermal conductivity on the heat transfer characteristics of phase-change energystorage wall
摘要
Abstract
The composite phase change material(PCM)with anisotropic shape is used as a plate,combined with the concrete layer of the wall,to construct the assembled wall of energy storage,and establish the two-dimensional heat transfer model of the wall.Through numerical simulation,the influence of the anisotropic thermal conductivity on the heat transfer performance of the energy storage wall is analyzed.The results show that the anisotropic thermal conductivity of the PCM has a certain diffusion effect on the heat accumulation on the wall surface of the PCM energy storage wall,and can reduce the heat load in the transverse(X-direction)heat transfer process of the wall.While maintaining the transverse unidirectional thermal conductivity unchanged,increasing the longitudinal(Y-direction)thermal conductivity is beneficial for enhancing the energy storage characteristics of the phase change wall.关键词
