Abstract
The SST k-ω model and turbulent Prandtl number model are used in this paper to simulate liquid lead–bismuth cross-flow and heat transfer in helical-coiled tube bundles with different helix angles. The numerical method is validated using relevant experimental data from previous research. The helix angle significantly influences the flow and heat transfer due to the flow pattern transition and continuously changing tube arrangements. The friction factor and Nusselt number both increase firstly and then decrease with the increase of the helix angle. The flow fields are analyzed from the perspective of velocity magnitudes, streamlines, vortex structures and turbulence intensities. The complicated flow structure induced by the helix angle significantly impacts the flow and heat transfer performance. The field synergy principle is applied to analyze the enhancement of heat transfer. The achievement in this paper can be a reference for numerical methods and design optimization of liquid metal H-OTSG.
