Numerical Analysis of Baffles Effect on Thermal Storage Capacity Inside Hot Water Storage Tank

In this contribution two dimensional numerical study was carried out in order to see the effect of baffles length on discharge time and thermal stratification in storage tank to be used in photovoltaic thermal hybrid system. Navier Stockes and energy equations are modelled using finite volume method. Focus is particularly on analysing the effect of baffles number having disc form placed in alternating rows on thermal stratification and discharge time. The found results revelled that the baffles optimal length in case of (B) configuration yielded the best thermal stratification and minimal discharge time. All in all, the current results agree to a large extent with those reported in literature.
