A Lightweight Dynamical Model For Packed Bed Thermal Energy Storages

Year: 2025

Type: conference-paper

Abstract: We introduce a computationally simple model for predicting the dynamical response of sensible heat packed bed thermal energy storages (TES). The proposed system of differential-algebraic equations arises from thermodynamic power balance considerations. We derive the governing equations and present model validation by Computational Fluid Dynamics (CFD). The numerical results demonstrate that the proposed model can accurately represent different flow configurations within the TES.
