| Abstract: | Summary A numerical model is proposed to describe the transient behaviour of a porous bed thermal accumulator. Attention has been focused on power production applications where minimum entropy generation in the charge process has to be considered a leading design criterium. The model is solved and the influence of various design parameters on the performances of the storage system are analysed. |
