Channel flow with multiple bumps at low Reynolds number

Channel flow with multiple bumps at low Reynolds number, starting from rest. The flow gets steady immediately, but showing "many" separation zones.

• Distribution of temperature/concentration via Boussinesq model
  
  

  Visualization via distribution of the concentration in the flow field, starting from the inlet, (first, shaded, 1.1 MB) and via temperature distribution from the heated walls (second, shaded, 0.9 MB).
