Pseudocolor plots of axial velocity in a bundle of seven wirewrapped pins at
Re=20000, based on pin diameter D. Uniform flow is specified at the inlet
and the flow transitions to turbulence by z ~ 0.5 H/D, where H is the wire pitch.
Simulation performed using 32768 processors with the spectral element code
Nek5000
on the IBM BG/P at the Argonne Leadership Computing Facility. Computing
time provided was through the DOE Office of Science INCITE program.
