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.
