Abstract

Abstract: Based on the computational fluid dynamics simulation, the flow characteristics of helium gas
in the pebble bed were preliminary investigated. The effect of the channel length of pebble bed and the
channel cross section of the pebble bed on the pressure drop of purge gas was analyzed in detail. In addition,
the pressure drop and Loss Coefficient of pebble beds with different packing structure at different flow rates
were obtained.

Key words: Pebble bed of tritium breeder, Flow characteristics, Pressure drop, Loss Coefficient
