  Study of 'Flow around a Heated Cylinder in a Channel

• Rectangular domain of length 2.0 and width 1.0
• one heated circle of radius 0.1 and located at x = 1.60, y =0.5
• inflow b.c.'s: constant velocity 1 at the left bottom edge i.e in between x=0, y>0 and x=0, y<1
• outflow b.c's: unknown at the right top edge i.e. in between x=2.0, y>0 and x=2, y<1
• Other b.c.'s: zero velocity at the fixed walls
• initial condition at t=0: starting from rest
• viscosity parameter: 1/nu=1,000

• coarse mesh (=level 1): 44 cells, 58 vertices, 248 d.o.f.`s
  

  
  
  

• uniform refinements with exact boundary adaption
• visualization on level 5: 11264 cells,11488 vertices, 56768 d.o.f.`s
• computational mesh on level 5: 11264 cells, 11488 vertices,56768 d.o.f.`s
• nonconforming nonparametric rotated bilinear fem's (meanvalue version), UPW

• equidistant time stepping for computation with k=0.01
• equidistant time stepping for visualization with k=0.25 (= 1 frame)
• Total time T=30 corresponds to 3,000 time steps
• fractional step theta scheme
