Résumé:
The aim of this work is the study using a CFD code, of the thermal stratification in two
solar tanks equipped with active stratification devices and having equal volume. The first one
equipped with three injectors with parallel plates spaced of 2 cm, while the second is equipped with
three parallel plates injectors spaced of 4 cm. The influence of flow rate is highlighted. Results show
that increasing the injection flow rate leads to a fast lose of stratification of the storage tank for
both solar storage tanks. Thus, for high injection flow rate, the stream creates along both sides of
the tank leads to a faster lose of stratification. The second tank with injectors more spaced preserves
better the stratification compared with the first tank
