A 150,000 gallons water tank of 33 m (100 ft)
hydraulic head supplies a gravity-fed horizontal open water channel. The
working section is 0.9144 m (1 yard) wide, 0.3 m (1 ft) high, 4 m (12 ft) long.
Operated as a water table, the water channel models by hydraulic analogy the
two-dimensional wave patter around objects in supersonic and hypersonic flow.
Water depth range 0-0.3 m, water speed range approximately 0-1 m/s. Test
section is glazed on both sides and on the floor. Instrumented by schlieren and
shadowgraph photography for wave visualization, piezometers, propeller flow
meter, dye injection, hydrogen bubble generator.
