In the advanced gas-cooled pebble bed reactors for nuclear power generation, the fuel is
spherical coated particles. The energy transfer phenomenon requires detailed
understanding of the flow and temperature fields around the spherical fuel pebbles. Detailed
information of the complex flow structure within the bed is needed. Generally, for computing
the flow through a packed bed reactor or column, the porous media approach is usually
used with lumped parameters for hydrodynamic calculations and heat transfer. While this …
