Abstract
The present investigation concern with the study on exergy loss and turbulent flow inside a round duct equipped with complex turbulator. The Copper oxide/H2O nanofluid at 0.04 particle volume concentration has been considered as carrier fluid. The tests were examined under the turbulent flow with Reynolds ranges of 5000 < Re < 15000. The duct has been conducted under constant heat flux of wall surface. Outputs indicates that flow blockage increases with augment of Re and b. Exergy drop is reversely proportional to the convective mode and therefore X-d declines with rise of tape width and Re. (C) 2019 Elsevier B.V. All rights reserved.
