Merger of three parallel pipe flows (same speed) at low Reynolds number

Computational details
Short description and remarks

Short description and remarks

Merger of three parallel pipe flows into a channel at low Reynolds number. The inflows through the inlets have the same parabolic profile. The resulting flow is symmetrical and steady in time. This simulation has to be compared with the similar ones in the Album, including higher Reynolds number and different types of inflows.


  • Distribution of temperature/concentration via Boussinesq model

    Visualization via tracing of concentration, starting from the inlet, shaded (first, 0.6 MB) and via isolines (second, 1.6 MB). The color red means `value of concentration +1' while blue stands for 'value of concentration -1'. Consequently, the green regions represent the mixed zones!

  • Pressure

    Visualization via pressure plots, shaded (first, 0.3 MB) and via isolines (second, 0.7 MB).

  • Streamfunction

    Visualization via streamline plots, shaded (first, 0.2 MB) and via isolines (second, 0.8 MB).

  • Velocity

    Visualization via vector plots (vectors, 0.6 MB) in a zoomed region.
