5 Numerical Models for Pebble-Bed Heat Transfer
Fig. 5.86 Fluid temperature (a) and particle temperature field (b) of the HTR-10 benchmark problem (sectional view)
Fig. 5.87 Particle temperature at the center line of the benchmark problem (z is the distance to the
top)
flow direction from top to bottom. The THERMIX is a widely accepted software
for engineering application [1, 59] since the incorporated empirical homogeneous
equilibrium code is based on sound experimental-measurements. Thus, it is used
here for analyzing the flow and heat transfer of HTGRs. It can be seen in Fig. 5.87
that present simulation by the Smoothed Void Fraction Method (SVFM) is in good
agreement with the THERMIX.
