Computational Details:

"Flow in a gas burner at low Reynolds number"

• see the description in http://www.featflow.de/ture/paper/raschrtu.ps.gz for the geometrical details
• inflow b.c.'s: constant with (maximum) velocity 1
• outflow b.c.'s: natural "do nothing" b.c.'s
• other b.c.'s: zero velocity at fixed walls
• initial condition at t=0: starting from rest
• viscosity parameter: 1/nu=100

• coarse mesh (=level 1): 302 cells, 376 vertices, 1,696 d.o.f.`s
  

  
  
  

• uniform refinements with exact boundary adaption
• visualization on level 4: 19,328 cells, 20,053 vertices, 98,128 d.o.f.`s
• computational mesh on level 6: 309,248 cells, 312,205 vertices, 1,555,149 d.o.f.`s
• nonconforming nonparametric rotated bilinear fem's (meanvalue version), UPW
