In 2005, S.H.Noie[2] indicated that the lowest effectivenessof heat exchanger would avoid the heat capacity rate equal to 1 according to simulation and experimental results.
Therefore, the case 3 was selected in the following simulations that to reducing computing time.
Fins pitch is the minimum impact parameter in this simulations (about 1%), because increasing pitch would reduce turbulent intensity in the heat exchange process.
