shown in Fig.5.85a, where z p is the z-coordinate of particle center position. The
sub-particle scale unstructured mesh scales (Fig. 5.85b) are used for the fluid phase
in the benchmark problem, where the cell-to-particle volume ratio χ is 0.2472.
It can also be seen from Fig. 5.86 on the steady-state result. The fluid is heated
by the fuel particles in the packed pebble bed. The temperature increases along the
