| Özet |
| In this study, the effect of the Reynolds numbers for different sinusoidal decoupled strip elements placed separately from the pipe in turbulent flow on heat transfer was investigated experimentally. Experiments were carried out under forced convection and constant heat flux conditions. Corrugated strip elements were positioned axially to the pipe center, which draws a sinusoid used as a turbulator. Experiments were repeated for three different amplitudes of sinusoidal strip elements with 3D/4 width, 3D/16, D/4, D/8. Experiments showed that although the strip elements enhanced heat transfer at different rates. As a result, it was seen that heat transfer ratio ie Nusselt number increased as the amplitude value increased. While this rate is 55% in D/8 amplitude, it was about 75% in 3D/16 and 105% in D/4. |
