Channel flow with two opposite symmetric bumps at low Reynolds number (same heigth)

Computational details
Short description and remarks

Short description and remarks

Channel flow with two narrowing sections at low Reynolds number, starting from rest. Both bumps are symmetric and opposite, and their height is 0.35, while the free section inbetween has width 0.3. The flow gets immediately steady.


  • Distribution of temperature/concentration via Boussinesq model

    Visualization via distribution of given concentration in the flow field, starting from the inlet (shaded, 1.0 MB).

  • Pressure

    Visualization via pressure plots, shaded (first, 0.7 MB) and via isolines (second, 0.4 MB).

  • Streamfunction

    Visualization via streamline plots, shaded (first, 1.1 MB) and via isolines (second, 0.8 MB).

  • Velocity

    Visualization via vector plots (1.0 MB).
