Abstract
The aim of this investigation is to investigate the H2O turbulent flow according to the nanoparticles, including copper oxide within a pipe outfitted by an innovative swirling flow generator. For the purpose of determining width effect in turbulent flow for Reynolds number, the results are analyzed. Moreover, relationships are obtained to estimate the irreversibility component. It is observed that viscous reduces directly proportional to pumping power. This means that following an increase in inlet velocity, differential pressure rises. Because of higher velocity gradient, by increasing width Sgen,f becomes greater. As turbulator with larger b is used, stronger turbulence intensity will be generated.
•Irreversibility and heat transfer simulation for nanomaterial is scrutinized.•Compound turbulator has been used to make secondary flow.•Sgen,f augments with augment of Re.•Irreversibility due to heat transfer declines with augment of b.
