高温气冷堆三通通道内石墨颗粒物沉积研究

Graphite particles carried in the flow of helium gas in high-temperature gas-cooled reactors will accumulate locally in the flow channel, which affects the operation of high-temperature gas-cooled reactors. Numerical simulation of particle deposition in the three-channels of the high-temperature gas-cooled reactor was carried out using ANSYS software, and the deposition movement of graphite particles was obtained; the results showed that the graphite deposition in the three-way tube mainly occurred in the main entrance stage, branch entrance stage, and main and branch pipelines Where the confluence Research on Graphite Particle Deposition in the Tee Channel of High Temperature Gas-cooled Reactoroccurs; the concentration of particles near the wall is lower; the graphite particles deposit less at the exit section after the confluence, and the particle deposition can be improved by increasing the flow rate.
