Abstract
In current context, turbulent flow with install of helical tape has been analyzed in a system in which nanofluid was utilized in shell side. Both hydrothermal and exergy analysis are presented. Hot gas and H2O-CuO nanofluid are considered as working fluids. FVM is utilized to explore the roles of Re, number of revolution (N) on hydrothermal treatment. Suitable correlations for entropy components are extracted according to obtained data. Radial velocity can be augmented with enhance of revolution and inlet velocity of nanofluid. So, friction augments and higher values of pressure drop can be achieved. Augment of revolution leads to augmentation of pressure loss about 95.25% and 81.42% depend on the values of Re. When revolution has highest value, pressure drop faces 389.4% augmentation with rise of Re. With assuming largest amounts of other variables, growth of Re makes outlet temperature to reduce about 8.4% while rise of N results in 0.73% augmentation in Tout. Assuming N=7, augment of Re leads to decline Xd by 64.29%. At Re⁎=5, growth of N up to 7 makes Xd to reduce about 62.43%.
