摘要：

This article reports on an analysis of the possibility of storing thermal energy in a rock bed. The calculations were made in Ansys CFX 18.0 CFD. The analysis determined the charging time of a packed bed of granite rocks in variable flow conditions for the assumed geometry of the energy storage system. The model was 2-dimensional, consisting of two domains connected by an interface. The packed bed was modelled using a porous model approach. The inlet velocity was varied in the range 0.254 m/s. The total charging time was 70 to 1100 min, depending on inlet velocity. © 2020. All rights reserved.
