Measurements of free-surface profile in transient flow with a simple light-slicing method
A simple light-slicing technique for the direct measurement of the free-surface shape h(x) in onedirectional transient liquid flows is studied. The method is used to determine h(x) with a precision of the order of 10−2 mm along a line several centimeters long, allowing for height differences of some...
