Abstract
This paper investigates the flow structure and thermal performance characteristics of the fluid flow through a heat exchanger tube fitted with perforated hollow cylinders (PHCs) under turbulent flow regime. The effects of the perforated index (0.08 < PI < 0.24), diameter ratio of the hollow cylinder (0.5 < d/D < 0.9) and Reynolds number (6000
