摘要：
The behavior of the graphite dust in the steam generator is important to the safety of High Temperature gas-cooled Reactor (HTR). The present study numerically investigates the effect of steam generator structure on deposition and diffusion of graphite dust particles in HTR, then the effect of helium velocity, tube spacing and graphite dust particle diameter on the deposition and diffusion characteristics of graphite dust are analyzed. The results showed that the flow field around the heat transfer tube is complex and high turbulence intensity; the deposition efficiency of the graphite dust will increase as the tube spacing increases, while the deposition efficiency of the graphite dust will decrease with the inlet velocity increases.
