Performance Analysis in Study of Heat Transfer Enhancement in Sinusoidal Pipes
Özet
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.
