Abstract:
A numerical investigation on turbulent nanofluid flow, heat transfer and
entropy generation behaviours in a constant heat-fluxed tube with inclined ring ribs
(IRR) has been performed. The computations are performed using a finite volume
approach with the couple algorithm for the mass flow rate of nanofluid (Al2O3-water)
in the form of Reynolds number between 4000 and 12,000. Effects of nanofluid with
1 percent, 2 percent, and 3 percent volume fraction (vf) on the rate of heat transfer, friction loss and
entropy generation are examined. The numerical result reveals that a pair of counterrotating
vortices produced by the IRR can induce impingement flows on the wall region
resulting in greater increase of the heat transfer above the plain tube alone, apart from
the nanofluid effect. The maximum thermal performance occurring at PR = 0.5, Re =
4000, and vf = 3 percent is about 2.03 and the entropy generation was lowest at this condition.
