Abstract: 

In current work, turbulent flow of H2O based nanomaterial flow containing copper oxide inside a pipe fitted with new swirl flow generator was examined. Outputs were examined to find the impact of width tape for the Reynolds number in turbulent regime. In addition, correlations were derived for predicting component of irreversibility. Outcome show that viscous loss has direct relationship with pumping power. Thus, increasing inlet velocity makes the differential pressure to augment. Owing to higher velocity gradient, Sgen,f augments with increasing width. Using turbulator with greater b leads to generate stronger turbulence intensity.
