Abstract
By adopting an appropriate near-wall function in a K-ε model, turbulent convective heat transfer in the 90o-bend tube with a straight tail section has been analyzed numerically for a low-Reynolds-number turbulent-flow regime. The results are presented in the form of velocity profile, temperature distribution, turbulent intensity distribution, friction factor and heat transfer for the condition of a heat flux constant. The proposed model of the near-wall function describes well the low-Reynolds-number turbulence field including a reverse transition mechanism.
