7 Applications: Pebble Flow Optimizations

Fig. 7.44 Cross-sectional velocity distribution in full-scale practically running pebble bed
diameter fill the silo up by random packing. The pebble bed runs in the practical
operating mode with about 3000 pebbles circulated one day, which is close to the
design mode of the HTR-PM being under construction. A 28-day-long period has
been simulated for three cases with different particle–wall friction setups “μ
cyl
p−w =
0.3, μ
hop
p−w = 0.3”, “μ
cyl
p−w = 0.1, μ
hop
p−w = 0.1”, and “μ
cyl
p−w = 0.3, μ
hop
p−w = 0.1”).
