Abstract

Abstract

In order to study the flow and heat transfer characteristics in the shell side of LBE Helical-coiled Once-Through Steam Generator (H-OTSG), a numerical method for the simulation of the LBE flow and heat transfer characteristics in helical tube bundles is proposed. Based on available relevant experimental studies, different turbulence models are validated. After validating the reliability of the numerical model, the shell side of LBE H-OTSG is simulated and the influence of velocity and helix angle on heat transfer and flow resistance characteristics are analyzed. The results show that the shell side flow resistance and heat transfer increase with the increase of flow rate and helix angle. An increase in velocity would make the flow fields more uniform. The increase of helix angle affects the vortex distribution and enhances the mixing. This study provides a reference for the study of flow and heat transfer characteristics and design optimization of LBE helical tube.
