Abstract

The present paper presents a comparison between the measured and predicted performance of a sensible heat storage unit. The storage unit is packed with spheres manufactured from a powder of certain type of Egyptiain clay (trade name “tafla”) produced at Abu-Siebera, Aswan. A special experimental set up was designed to predict the performance of the storage unit. The temperature distribution of the solid spheres was measured at different mass flow rates and at different time intervals. A comparison was made between these measured values and the corresponding values obtained using a numerical model based on finite difference techniques. The results showed a reasonable agreement between the measured and predicted temperature distribution. Finally, the pressure drop through the storage unit was measured and compared with the corresponding pressure drop calculated using two different empirical formulae.
