Abstract Heat exchangers are widely used to transfer heat from one fluid flow to another. Over time, various types of heat exchangers have been developed to decrease energy consumption and increase efficiency, including compact fin tube and double tube with special inner pipe geometries (ribbed, spiral, and petal shapes) [1, 2]. In this study, we experimentally investigated the heat transfer efficiency of petal-shaped double tubes with a large wetted perimeter or heat transfer area. Moreover, the influence of the number of petals was studied. Our results show that a larger heat transfer area improves heat transfer rate in heat exchangers but the heat transfer efficiency of the five petal-shaped double tube (5P-tube) is much higher than that of the 6P-tube because of a smaller flow resistance of the 5P-tube.
