A comparative study and results analysis performed for evaluating the entropy generation
through corrugated plate heat exchanger by using Nano particles of MWCNT dispersed in DI
water, using three different concentrations of MWCNT of 0.25 g/liter, 0.5 g/liter and 1 g/liter.
Besides, the variation of the hot Nano-DI water inlet temperature at Th,i= 500C, 600C, 700C
and 800C; by varying the volume flow rate of the hot Nano-DI water side at Ѷh = 1 LPM, 2
LPM, 3 LPM, 4LPM and 5 LPM, and varying volume flow rate of the cold water side at Ѷc =
1 LPM, 2 LPM, 3 LPM, 4LPM and 5 LPM. The total entropy generation "Sgen" increases with
the increase of the volume flow rate of the hot fluid side. Moreover, the total entropy
generation increases by increasing the inlet temperature of the hot fluid side. Moreover, the
total entropy generation decreases with decreasing the volume flow rates of the cold fluid
side. Also, the total entropy generation increases by increasing the Nano particles
concentration in the DI water, except for the 0.5 g/liter, it shows lower values for the total
entropy generation. However, the 1 g/liter Nano-DI water reaches 155% increase over the DI
water, at 800C.
