Abstract: Twisted tapes are used to rise the amount of the heat transfer in pipes. In this study, the heat transfer was studied numerically in horizontal pipe with normal twisted tape inserted and two modified twisted tapes. Nine different values of fluid velocity were used (0.15, 0.2, 0.25, 0.3, 0.6, 0.65, 0.9, 0.95 and 1.3 m/sec), the flowing fluid through the pipes was γ-AL2O3/Water nanofluid. ANSYS Fluent 15.0 combined with k-epsilon turbulent model was used for simulations, the model was validated using the classical formula of Dittus-Boelter. The results from the simulations were established to be in good agreement with the formula results.
