Analyzing entropy and thermal behavior of nanomaterial through solar collector involving new tapes

In the present examination, the effect of Aluminum oxide suspended in water at concentration of 0.03% as nanomaterial for turbulent flow using multiple twisted tapes (TT_n) in a solar flat plate collector was scrutinized. Properties are estimated by utilizing previous correlations. Outputs are described for a different number of turbulator and Reynolds number (Re). The increase in S_gen,f (1604.672) is more significant for higher Re = 20,000. The highest S_gen,th (15,788.13) is observed for TTn = 1 and Re = 4000. The highest number of Be is 0.9987 when the TT_n = 1 and Re = 4000. Both the Be number and the Фs shows the same trend for the reported results. The increase in the number of Re and TT_n reduces the values of Be and Фs. Output results verify that the use of turbulators enhances the nanofluid flow resulting in enhanced heat transfer, which also provides higher flow disturbance. Therefore, it can be concluded that using twisted tapes and nanofluids can result in reduces exergy losses.
