## Abstract Experiments have been performed for turbulent channel flow over a backwardโfacing step. The backwardโfacing step is controlled by equipping a slit at the bottom corner of the step. Low momentum fluids in the recirculation region are sucked or high momentum fluids are injected from the s
The study investigates the entrance effect for ยฏow over a backward-facing step by comparing predictions that set the inlet boundary at various locations upstream of the sudden expansion. Differences are most signiยฎcant in the sudden expansion region. If the geometry has an inlet channel, then shorte
