Abstract

In this study, a performance analysis of the sinusoidal pipes with various
amplitudes (in constant period) and various periods (in constant amplitude)
have been performed by utilizing non-dimensional entropy generation equation
(Ns) mathematically developed for constant wall temperature thermal boundary
condition. According to the performance analysis based upon the characteristics
obtained in experimental study; for laminar flow 2Sin 0.25X pipe shows the
best performance in constant period while Sin 0.5X and Sin X pipes show the
best performance in constant amplitude. For turbulent flow the all-sinusoidal
pipes show nearly the same performance as the straight pipe in constant period
while Sin 0.25X and Sin 0.5X pipes show the best performance in constant
amplitude.
