Analytical description of thermocline tank performance in dynamic processes and stand-by periods

(in lingua inglese)

In this work a Logistic CDF has been used for predicting the behavior of thermocline tanks when consecutive charge and discharge processes are performed and also during stand-by periods of no operation. This Logistic-CDF is expressed in dimensionless coordinates and has been already parameterized in terms of working conditions. With the help of experimental results reported in the literature we have demonstrated that the Logistic-CDF is able to predict the behavior of real thermocline storage tanks not only when the storage medium is a liquid but also when it is a combination of a liquid and a solid filler.
