The Graphite Particle Movement in Fuel Handing System Bend Pipe in the High Temperature Gas-Cooled Reactor Available to Purchase

A typical bend pipe in the fuel transporting and refueling system in the HTR is studied. The helium three-dimension flow field in the bend pipe is simulated and the graphite dust particle movement and impingement in the helium flow field are researched by numerical simulation. The trajectories of graphite particles with different diameters and different initial positions are simulated. The position and probability of the graphite particle collision is studied by the numerical simulation on the particle movement.
