Emerson Cavitation Tunnel

Virtual Tour, Emerson Cavitation Tunnel

The Emerson Cavitation Tunnel was originally installed in the School of Marine Science and Technology in 1949 and entered service in 1950-51. The tunnel was completely modernised in 1980, and was further equipped with modern flow measurement systems in 2000. An enhanced measuring section with higher speed capability and matching control systems was installed during 2007.

The Emerson Cavitation Tunnel provides an efficient service to the marine
sector, including ship owners, shipyards and propeller manufacturers.
As well as commercial consultancy services, the Emerson Cavitation Tunnel,
which is the only cavitation tunnel in the UK, offers background research and
development services to academia for cavitation, noise, propulsion, turbines,
coatings and hydrodynamics related activities.

The tunnel maintains its own scientific and technical staff, with comprehensive mechanical, electrical, electronic and model making technician support from
within the School of Marine Science and Technology.

Testing Capabilities

  • Conventional and unconventional propeller performance tests, including shaft inclination in three axes
  • Cavitation and noise tests in uniform and non-uniform streams
  • Wake simulation using wake screens and flat plate pressure pulse
  • Emerson Cavitation TunnelWake simulation using dummy hull model including hull surface pressure measurements
  • Tidal/current turbine performance, cavitation and noise tests
  • Flow measurement and analysis using 3D LDA/PDA and stereoscopic PIV systems
  • Boundary layer and drag tests with flat planes, submersible bodies and propellers with coatings
  • Load measurements with submerged bodies
  • Propeller testing in simulated ice blocks
  • Recording of nature and extent of cavitation using still and high-speed video cameras Emerson Cavitation Tunnel
