The main data of the Cavitation Tunnel is as follows:
Pressure regulation from relatively high vacuum to above atmospheric pressure measured at the pressure regulation container 1 bar Approx
Cavitation number adjustable in wide range down to belows = 0.2
Total length including stiffening girder not including the length required for the impeller drive 20.4 m Approx.
Measuring section 850 mm x 850 mm
Length of measuring section 4000 mm
Contraction ratio of the nozzle 4.99:1 Approx.
Maximum velocity of the water in the measuring section 12 m/s
Total height from the floor at which the tunnel foundations are supported to the highest part of the cavitation tunnel, inclusive stiffening girders, not including additional height for the separate pressure regulation container and not including the height for setting in propeller dynamometers or other test equipment 12.9 m.
The dynamometers have been designed for low friction torque at the propeller shaft and for this reason shaft seals are not fitted. As a result, the dynamometers are not watertight. If watertight propeller dynamometers are required, alternative designs are available. All dynamometers have a similar appearance although vary in size / rating to suit the intended specification required. The Dynamometers are compact with low weight and small dimensions and as such are suitable for use with models over a wide range of sizes however also offer with suitable accessories the ability of mounting two dynamometers driven through a gear box to allow the testing of twin screw models. The self propulsion dynamometer measures thrust and torque of the propellers during propulsion tests with ship models on smooth water and in waves in towing tanks.

Proton Exchange Membrane Fuel Cell incorporates a unique membrane electrode assembly for the stack cells, each of which is internally reinforced and water cooled. The Proton Exchange Membrane fuel cell is one of the current leading contenders as a power source for use in motor vehicles. The fuel cell generates electrical power directly from hydrogen and air producing only pure water and heat as a by-product.
This gives the cell a high watt density and allows students to investigate a practical fuel cell with a realistic output capable of driving significant electrical loads up to 0.75kW. Unlike other educational units on the market the Proton Exchange Membrane Fuel Cell utilises an award winning module that is identical to those used in an actual vehicle power supply currently in production.
They are suitable for a range of hydrodynamic research functions, from current meter calibrating to large ship model testing at speeds of up to 20m/s. All carriages are designed such as to cope with steady state and dynamic model testing, whilst ensuring smooth running at constant speeds. Our range of Carriages often incorporate four quadrant systems for smooth acceleration and retardation. Towing Carriages are manufactured from modern high-grade materials offering rigidity and strength, but where necessary manufactured in suitable lightweight materials for high-speed applications. Drive trains, electrical systems, control equipment and other important key components are selected in order to reduce overall maintenance costs and down time during routine maintenance. Software control maximises test duration in calm water and with links to wavemakers can maximise test duration in waves.

Beams are important design elements in mechanical engineering and building construction that can deform under load. In linearelastic material behaviour, the bending line, also known as elastic line, is used to determine the deflection of beams. Deflection can be determined at any point on the beam using the influence coefficients and commutative theory. Beams are subjected to load transversely in the axial direction, which leads to deflection.
Features:
Beams of different materials: steel, brass and aluminium.
Learning Objectives And Experiments:
Elastic line and support forces in statically indeterminate systems.
Elastic line under varying load.
Elastic line under various support conditions.

Electronic measuring system
Hydraulic system

This accessory set-up enables the response of an elastic rotor to unbalanced excitation to be studied. The field balancing of elastic rotors is another area which can be investigated. The supplied pendulum ball bearings ensure full mobility of the shaft. The subcritical, supercritical and resonance running states can be demonstrated. A comparison of the orbits (path curves) in the subcritical and supercritical range is of particular interest. The retainer bearing limits the amplitudes to harmless values at speeds close to resonance.
