Study of heat and mass transfer in a channel with fins based on a triply periodic minimal surface

Abstract

Presents a methodology for studying heat and mass transfer in the channels of heat exchange devices, where fins made in the form of a Schwarz Primitive triply periodic minimal surface (TPMS) are used to intensify heat transfer. The solution of the heat and mass transfer problem is carried out using the finite element method in the Fluent module of the ANSYS software package. The work examines the influence of the initial flow velocity, as well as the thickness of the TPMS fins on the pressure loss and temperature characteristics of the flow. The study showed that TPMS fins enhance heat transfer and create turbulent flows in close to the TPMS frame. The pressure loss in the channel increases according to a power law with increasing initial flow velocity. The results obtained in this study demonstrate the potential of using TPMS in heat exchange devices and open many prospects for further research.
