Channel flow with two bumps at high Reynolds number (nonsymmetric location)

Computational details
Short description and remarks

Short description and remarks

Channel flow with two narrowing sections at high Reynolds number, starting fully developed. Both bumps are at different locations: the height of the lower hill is 0.35, while the upper one has heigth 0.25. The flow shows a complex behaviour which - in addition to the medium Reynolds number case - exhibits oscillations after the first bump.


  • Distribution of temperature/concentration via Boussinesq model

    Visualization via distribution of the concentration in the flow field, starting from the inlet, but with different color maps (first, shaded, 1.5 MB, second, shaded, 1.9 MB).

  • Pressure

    Visualization via pressure plots, shaded (first, 1.2 MB) and via isolines (second, 5.7 MB).

  • Streamfunction

    Visualization via streamline plots, shaded (first, 1.4 MB) and via isolines (second, 6.2 MB).

  • Velocity

    Visualization via vector plots (11.4 MB) in a zoomed region.
