Computational Details:

Study of 'Shell and Tube' Heat-Exchanger exhibiting different tube arrangements

• square domain of length 4
• 25 circles of radii 0.06
• Dirichlet b.c.'s for the u-velocity: u=1 at x=0, y<1
• natural "do nothing" b.c.'s for the velocity: x=4, y>3
• initial condition at t=0: starting from rest
• viscosity parameter: 1/nu=10,000

• coarse mesh (=level 2): 1936 cells, 2100 vertices, 10,056 d.o.f.`s
  

  

• uniform refinements with exact boundary adaption
