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 D/2
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 i.e. 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.
