Computational Details:

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

• squared domain of length 4
• Four heated circles of radius 0.375 with the first circle located at x=1.33 and y=1.33
• 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=1,000

• coarse mesh (=level 2): 208 cells, 248 vertices, 1120 d.o.f.`s
  

  
  
  

• uniform refinements with exact boundary adaption
