A unitary pebble bed was built to analyze the flow characteristics of purge gas based on DEM-CFD method. Flow characteristics between particles were clearly displayed. Porosity distribution, velocity field distribution, pressure field distribution, pressure drop and the wall effects on velocity distribution were studied.
