Static mixer example used for benchmarking

This example contain the static mixer examples of our code. So far only the design by Casper Schousboe Andreasen is here for reference.

PetSC Static mixer design

Details:

• Domain: Duct of dimension 4 x 1 x 1
• BCs:
  • Inlet (x=0): Parabolic velocity profile, u_max = 1, v = w = 0 (Currently constant)
  • Two inlets for temperature:
    • Bottom half (z < 0.5): Dirichlet, T = 0
    • Top half (z >= 0.5): Dirichlet, T = 1
  • Walls (y=0, y=1, z=0, z=1): No-slip, Neumann for thermal.
  • Outlet (x=4): Pressure outflow.
  • Initial condition: Fluid at constant velocity u = 1, v = w = 0
• Re = 0
• Pe = 2000
• Brinkman IBM for solid obstacles.
  • Max restriction = 100
  • Min restriction = 0
