Flow over steps

The following examples concern channel flows over steps.

Near the step, the flow separates and produces complex flow patterns, oscillating in space and time. The complexity of the problem depends on the:

• inflow speed
• viscosity
• size and shape of the step, in relation to the channel geometry

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

• "Comparison of Backward Facing Step flows" at different Reynolds numbers (comprehensive version)
• "Comparison of Forward Facing Step flows" at different Reynolds numbers (comprehensive version)

• "Backward Facing step" at low Reynolds number
• "Backward Facing step" at medium Reynolds number
• "Backward Facing step" at high Reynolds number
• "Inclined Backward Facing step" at high Reynolds number

• "Forward Facing step" at low Reynolds number
• "Forward Facing step" at medium Reynolds number
