The Emerson Cavitation Tunnel has its own scientific and technical staff, with comprehensive mechanical, electrical, electronic and model-making technician support from within the School.
It is used by many in the marine sector, including:
- ship owners
- propeller manufacturers
As well as commercial consultancy services, it offers background research and development services for:
- hydrodynamics related activities

Bruel & Kjaer 8103 miniature hydrophone and associated instruments.
In a water filled, thick walled steel cylinder placed on a 30mm Perspex window above propeller.
The Tunnel can be used for a variety of experiments.
Conventional and unconventional propeller performance tests, including shaft inclination in three axes.
Boundary layer and drag tests with flat planes, submersible bodies and propellers with coating.
Propeller testing in simulated ice blocks.
The Tunnel can be used to test wake simulation using:
- wake screens
- flat plate pressure pulse measurements
- a dummy hull model (including hull surface pressure measurements)
Cavitation and noise tests
Cavitation and noise tests can be conducted in uniform and non-uniform streams, and tidal/current turbine performance can be studied.
Measurements and recording
Flow can be measured and analysed using 3D LDA/PDA and stereoscopic PIV systems.
Load can be measured with submerged bodies.
The nature and extent of cavitation can be recorded using still and high-speed video cameras.
