Abstract

In this study the effect of perforated conical turbulators on heat transfer, friction factor and thermal performance of the heat exchanger is estimated through investigation. The different parameters used for the experimentation includes, fixed diameter ratios (d/D= 0.5), pitch ratios (l/D= 1,2,3) and number of perforation hole (N= 0, 2 & 4). The experiments were conducted in the range of Reynolds number lying between 3,000 to 21,000 with a test section of 1.5 m length pipe made of copper with a hydraulic diameter (D) of 68 mm. It was observed that Perforation played a major role in controlling the friction factor
