摘要
Abstract
Additive manufacturing enables precise fabrication of complex topological heat transfer structures,supporting compact and lightweight heat exchanger design.Triply Periodic Minimal Surfaces(TPMS)offer smooth channels,high sur-face area,and self-supporting geometry,which are advantageous for advanced nuclear systems.The effects of geometry and porosity on helium-xenon heat transfer remain unclear.A turbulence Prandtl number model suitable for low-Prandtl-number helium-xenon flow was developed from experimental data.Single-channel models of Gyroid(G)and Fischer-Koch S(FKS)structures were constructed to study flow and heat transfer behavior under different porosities.Numerical results showed that,at the same porosity,the FKS structure had an over 70%larger surface area and over 25%higher heat transfer effi-ciency than the G structure.Increasing porosity enlarged the channels and reduced pressure loss but weakened convection,while decreasing porosity enhanced shear and turbulence but increased resistance.The results clarify how TPMS geometry and porosity influence thermal performance and provide guidance for additive-manufactured heat exchanger design.关键词
