The William B. Morgan Large Cavitation Channel (LCC) is located in Memphis, TN, and is one of the world's largest and most technically advanced high-speed, variable-pressure water channels. Its sophisticated design permits the U.S. Navy to measure submarine and surface ship power, efficiency, and propeller noise by using models in a controlled but realistic environment.
As a model is held stationary, water flow at speeds up to 35 knots combines with variable pressure to allow simultaneous measurements of propeller cavitation and acoustics from the models propulsion, hull, and appendages. This facility is capable of performing tests involving cavitation, force measurement, flow visualization and noise on complete hull-appendage propulsor models, bodies of revolution, surface ships, submarines, and torpedoes; open water propeller tests; basic and applied research requiring low background noise levels, large Reynold's numbers, variable pressure and low turbulence levels.
The Large Cavitation Channel is a vertical plane, closed recirculating 1.4 million gallon, variable speed, variable pressure, channel with lower half submerged in 2.5 million gallon water filled trench, plus numerous other acoustic treatment features, 6:1 contraction ratio, aeration/deaeration system, filter system (5-micron), temperature control, stainless steel shell, models mounted on large removable test top, low turbulence (0.1%). High speed capability up to 50 ft/s. Large test chamber with 10 ft by 10 ft cross-section and a 13.1 m (43 ft) working length. Pressure in the LCC test section ranges from less than atmospheric to four times atmospheric pressure, the equivalent of water approximately 100 feet deep.
