Abstract

Heat exchangers have a wide range of applications and can be found in a variety of different industries, including chemical reactors, nuclear power plants, and solar energy generation. It is required to do thermal optimization on heat exchangers in order to decrease the size, cost, and energy requirements of the heat exchangers while simultaneously improving their capacity to transmit heat. In these types of businesses, heat exchangers frequently make use of corrugated pipes as piping material. They are put to use in the process of transferring heat across fluids that are maintained at varying temperatures. The flow of corrugated pipe was investigated by using different corrugated ring diameters, maintaining a corrugated ring angle of 360°, and keeping the spacing between the corrugated rings at 7.5 mm. At a Reynolds number of 5000, the focus of the study was on determining how the diameter of the ring effects the thermo-hydraulic flow of water. Utilizing various forms of numerical simulation, this study determined the thermo-hydraulic flow behaviour and the enhancement of heat transfer of fluid that was moving through a corrugated pipe while a constant heat flux was present. An enhancement in heat transfer coefficient can be confirmed because increase in turbulent kinetic energy was seen. There has been discussion over the impact that the diameter of the corrugated ring has on the behaviour of variables such as velocity, pressure, radial velocity, axial velocity, temperature distribution, and turbulent kinetic energy (TKE).
