The governing equations were solved by using finite volume approximations for a wide range of (0.06 < e/H < 0.26) and Reynolds numbers (5400 < Re < 23000), with a more concern on using the more adequate turbulent model. The computed results demonstrate the noticeable effects of this character on the heat transfer performance as well as the pressure drop to achieve the most effective and optimal corrugation design. In addition, RNG  turbulent model has better agreement with the experimental data.
