Subject(s): Online resources: In: International Journal of Heat and Mass TransferSummary: In this study, the influence of inlet geometry on the degree of stratification attainable in thermocline thermal energy storage is investigated. The turbulent mixing caused by different inlet geometries is quantified using a mixing index introduced in a one-dimensional flow model. The mixing index is correlated with the flow parameters for three different inlet configurations. Based on the obtained correlations it is concluded that the inlet geometry starts to influence thermal stratification in a thermocline thermal storage tank for Richardson numbers below 3.6.
