【 摘 要 】

This work is a contribution to the numerical study of the thermal behavior of a thermocline storage system. The energy conservation equations associated with their boundary conditions, have been solved numerically in the two filed media solid (rock) and fluid (HTF) constituting the packed bed thermal energy storage (TES). A parameter study of the packed bed dimensions, fluid flow rate, particle diameter and the ratio HD were carried out to evaluate the charging/discharging profiles of storage system. The results have been validated and they are in good agreement with the literature.
