| Abstract: | Solar power generation using direct steam generation technology requires cost-effective latent heat storage sys- tems.Therefore,a new method of improving heat transfer in the high temperature thermal energy storage system(HTIES) using graphite foils was presented.Two-dimensional transient simulations were performed by Fluent software.Moreover, a series of numerical calculations were implemented to assess the effect of geometrical and thermal parameters of the sys- tem on the performance expressed in terms o... |
