DNS of surface mounted cube in a channel, Reh=7250



- Mesh size: 16 millions of nodes (400x200x200)
- 2-nd order discretization
- 300 CPU of MareNostrum supercomputer of BSC
- Performed by F. X. Trias and A. V. Gorobets at CTTC UPC.
- CFD code SCH3D
  • Reynolds number Reh=7250 (based on the cube height)
  • Boundary conditions: constant analytical velocity profile on the input, non-slip horizontal walls, periodic in the spanwise direction
  • Non compressible newtonian fluid

DNS results should be found at CTTC UPC web site.
