摘要：
Graphite dust has an important effect on the safety analysis of high-temperature gas-cooled reactor (HTR). The flow field in steam generator was studied using computational fluid dynamics (CFD) method, and the resuspension of graphite dust in steam generator was analysed. The results show that the resuspension fraction is nearly zero for the particles with the diameter of 0.1 μm, while it increases as the helium velocity in steam generator increases for the particles with the diameter larger than 1 μm. The results also indicate that the resuspension fraction would increase as the diameter of the graphite dust increases at a given helium velocity.
