Channel flow with hills and bumps

The following examples concern channel flows over hills and bumps.

Due to the complex geometries, the flow shows many separations and produces complex flow patterns, oscillating in space and time. The complexity of the problem depends on the:

  • inflow speed
  • viscosity
  • size, shape and position of the hills and bumps in the channel

A systematic variation of these different configurations is part of the following flow situations.
