摘要

该文采用四参数随机生长模型构建气凝胶微观结构

通过蒙特卡洛方法模拟计算板状气凝胶的太阳消光系数

并基于格子玻尔兹曼模型预测其导热系数

系统分析孔隙率和微粒直径对光热性能的影响。结果表明

孔隙率和微粒直径对太阳消光系数的影响更为显著

且孔隙率对导热系数的影响大于微粒直径

孔隙率减少约12个百分点可使导热系数减小约25%

而微粒直径变化对导热系数的影响可以忽略不计。最后

结合动态传热模型

对寒冷地区（以郑州为例）建筑能耗进行模拟

发现具有较大孔隙率和微粒直径的气凝胶玻璃可降低约34%的能耗。

Abstract

This study employs the quartet structure generation set to construct the aerogel microstructure. The solar extinction coefficient of monolithic aerogel is simulated using the Monte Carlo method

and its thermal conductivity is predicted based on the Lattice Boltzmann model. The effects of porosity and particle diameter on the optical-thermal performance are systematically analyzed. The results indicate that porosity and particle diameter exert a more significant influence on the solar extinction coefficient

while porosity has a greater impact on thermal conductivity than particle diameter. Specifically

a reduction of approximately 12% in porosity leads to a reduction of about 25% in thermal conductivity

whereas the effect of particle diameter on thermal conductivity is negligible. Finally

building energy consumption in a cold region （taking Zhengzhou as an example） is simulated using a dynamic heat transfer model. It is found that aerogel glazing with larger porosity and particle diameter can reduce energy consumption by nearly 34%.
