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

Computational details
Short description and remarks

Short description and remarks

Merger of two perpendicular pipe flows. The left flow has speed 1 as well the lower one. Both merge, producing quite complex flow patterns. This simulation has to be compared with the similar ones in the Album, including higher 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, 1.9 MB and 2.6 MB, third as a zoom, 2.8 MB).

  • Pressure

    Visualization via pressure plots, shaded (first, 1.5 MB) and via isolines (second and third, as zoom, 3.6 MB and 9.9 MB).

  • Streamfunction

    Visualization via streamline plots, shaded (first, 2.1 MB) and via isolines (second and third, as zoom, 4.5 MB and 6.6 MB).

  • Velocity

    Visualization via vector plots (vectors, 8.0 MB). The zoomed area is visualized in the original position of the grid points.
