Merger of two perpendicular pipe flows (different speed I) at medium Reynolds number

Merger of two perpendicular pipe flows. The left flow has speed 1 and the lower one 5. Both merge, producing quite complex flow patterns. This simulation has to be compared with the similar ones in the Album, including different speeds for the lower inflow.

• Distribution of temperature/concentration via Boussinesq model
  
  

  Visualization via tracing of concentration, starting from the left and lower inlet (first and second, different color maps, 2.3 MB and 3.3 MB, third as a zoom, 4.8 MB).
  

  
  
  

• Pressure
  
  

  Visualization via pressure plots, shaded (first, 1.7 MB) and via isolines (second and third, as zoom, 5.3 MB and 9.1 MB).
  

  
  
  

• Streamfunction
  
  

  Visualization via streamline plots, shaded (first, 1.8 MB) and via isolines (second and third, as zoom, 7.0 MB and 10.1 MB).
  

  
  
  

• Velocity
  
  

  Visualization via vector plots (vectors, 11.9 MB). The zoomed area is visualized in the original position of the grid points.
