High Reynolds Number Turbulent Boundary Layer Flow over Small Forward Facing Steps
Measurements were made on three forward steps with step height to boundary layer ratio of approximately 3.8%, 15% and 60% and Reynolds number based on step height ranging from 6640 to 213,000. The measurements included mean wall pressure, single and 2 point wall pressure fluctuations, single and 2 …

Experimental and numerical studies of flows over forward facing steps in pressure gradients
… (APG) and Reynolds numbers on flows over forward facing steps (FFS). For the experimental work, particle image velocimetry was used to conduct velocity measurements at several locations downstream of the FFS. Proper orthogonal decomposition and two-point correlation were applied to the …

Experimental study of turbulent boundary layer flows over forward facing steps with different surface conditions.
… different surface types on turbulent flows over forward facing steps. A particle image velocimetry technique was employed to conduct field velocity measurements at the mid-plane of the test channel at selected locations downstream to 68 step heights. Three surface conditions were investigated. A …

Sound Radiated from Turbulent Flow over Two and Three-Dimensional Surface Discontinuities
… of far field sound from two-dimensional forward facing steps, gaps with rounded corners and swept forward facing steps with rounded corners were made. The sound from a forward facing step is shown to exhibit effects of non-compactness. Rounding the step corner results in consistent drop …
