Fig. 6.2.3.4 Nek5000 simulations at a Reynolds number of 10,000 in a 61-pin rod bundle.
Periodic streamwise boundary conditions. Contour plot of the instantaneous velocity
in the streamwise direction.

Fig. 6.2.3.5 (A) Nek5000 LES (solid line) comparison against experimental data (dots) for a
6-pin rod bundle in a central channel (streamwise velocity). (B) Image of the bundle
at Texas A&M.
