The complex of cavitation tunnels is intended for measuring hydrodynamic and acoustic characteristics of conventional and special- type propellers in open water and in wakes behind model hulls, as well as cavitation flow patterns around high-speed vehicles and their components.

Diameters of CT test sections range from 0.3 tо 1.3 m and flow speed ranges from 10 tо 30 m/s.

Large Cavitation Tunnel

Test Scope:

• Hydrodynamic and acoustic tests of open-water propeller models measuring up to 0.6 m in diameter
• Self-propulsion tests of fully submerged models and propellers in non-uniform flow with measurement of acoustic propeller characteristics
• Measurement of pressure fluctuations induced by propellers in cavitation and sub-cavitation conditions

Specifications:

• Test section: 1.3×1.3 m;
• Maximum speed: 13.0 m/s;
• Minimum cavitation number: 0.5.
