Pseudocolor plots of axial velocity in a bundle of seven wire-wrapped 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. For more information see the 2008 Scidac article or follow the links to the SHARP webpage.
