Abstract
Heat transfer enhancements is of the utmost importance in the design and deployment of advance energy systems, molten salt reactors, fusion devices, and concentrated solar power plants. In this work, the pressure drop performance of an additively manufactured twisted tape insert was tested at various Reynolds numbers in laminar, transitional, and turbulent regimes of flow. Friction factor data from additive manufacturing twisted tape insert was compared with existing correlations of twisted tape inserts obtained using traditional manufacturing techniques. As additive manufacturing is a promising technology with a wide range of applications, this paper discusses the design considerations and techniques required to build functioning additive manufactured test sections for thermal hydraulic research. Initial tests are done with twisted tape geometries similar to the ones found in literature, to study the effects of the manufacturing processes, and we acknowledge the capability of additive manufacturing to create designs that otherwise could not be fabricated. These data inform existing and future friction factor correlations for twisted tape swirl flow, impacting the development and deployment of this technology in advanced fusion, fission, and solar power plants. Through this process we demonstrate the applicability of additive manufacturing for heat transfer enhancements in heat exchanger geometries and discuss the potential advantages thereof.
