摘要

本文对labscale填充床蓄热系统进行了数值模拟。在直径0.30 m、高度0.90 m的填料床中，采用由拆除垃圾形成的单型储存颗粒。合成导热油在80 ~ 180℃之间作为流体相使用。比较了Schumann模型和一维连续相模型。为了实现两种不同的数值模型，假设充填床的长度被划分为90个相等的层。两种数值模型均显示出光滑的温度分布。数值结果与实验数据的比较将在今后的工作中进行研究。关键词:填料床;蓄热;数值模拟

Numerical Model of Lab-Scale Packed-Bed Thermal Energy Storage System

This paper presents numerical modeling of labscale packed bed thermal energy storage (TES) system. In the packed-bed with 0.30 m diameter and 0.90 m height, monotype storage particles developed from demolition wastes are used. Synthetic thermal oil is be used as fluid phase between 80 – 180°C. Schumann and one-dimensional continuous phase models are compared. To perform the two different numerical models, it was assumed that the length of packed bed was divided into 90 equal layers. Both numerical models showed smooth temperature profiles. Comparison of numerical results with experimental data will be studied in the future work. Keywords—packed-bed, thermal energy storage, numerical modeling
