Abstract

Abstract

The complex working environment of the fuel elements in the reactor may cause changes in the performance of fuel elements and deviations from their initial geometric state, which can affect flow and heat transfer characteristics and threaten the safety of the reactor core. In this paper, the ANSYS Workbench numerical simulation platform was used to establish a model containing four coolant channels, and the steady-state numerical simulation was carried out considering different bending conditions in the solid domain. The results show that the coolant flow is redistributed among the four channels under different bending conditions, thus affecting the temperature in the channel with a small flow section area increases significantly, and the highest temperature point in the solid domain shifts from the central region to the channel with a reduced flow area.
