  Large Flow Channel

  The Large Flow Channel is designed for a variety of experiments in the area of open flumes such as, for example, weirs, overflows, locks, oceanography and off-shore technology (including experiments on waves, measures for coastal protection such as dykes or beach simulations).It reaches an experimental length of 16m. The side panels are made of hardened glass to permit a virtually unobstructed view. The water supply is provided by several tanks. These are connected to the system such that they can also be used as a walkway so that the user can reach every part of the measured section. As soon as the tanks are connected together and to the channel itself, they provide an adequate water supply that, once filled, is independent of the local water mains. The inlet, outlet and tank are made of GFRP to combine high strength and a long service life with low weight. Because the unit can be set up anywhere, its suitability to specific local conditions is guaranteed.

  Ground Water Flow

  This unit for the investigation of ground water flows and drainage processes is fitted to a trolley. It consists primarily of a plastic tank that is filled with fine gravel for the experiments. Inlet and outlet pipes facilitate the production of a flow of water through the layer of gravel. Measuring connections are fitted to the base of the tank, these are connected to tube manometers using hoses so that the water levels can be displayed on a measuring station. Inserts supplied with the unit facilitate the simulation of excavations and wells. The gravel filling is not included.

  Multi-Purpose Teaching Flume

  Using the Multi-Purpose Teaching Flume in conjunction with the comprehensive accessories, the behaviour of flows can be demonstrated in numerous experiments. This makes it possible for researchers and students to carry out experiments, above all, in the area of open flume structures in hydraulic engineering. The measuring section of the base unit is 2.5 m long and has transparent side walls. This can be extended to 5 m by adding an additional element. Important elements of the Multi-Purpose Teaching Flume are the specially shaped inlet area by means of which a homogeneous flow is obtained, a centrifugal pump for setting up the water circuit, a flow rate measuring device and a manual inclination adjustment mechanism designated to compensate flow losses or to simulate natural slope.

  Ship Vibration Apparatus

  The is used to investigate the dynamic behaviour of a ship structure. It therefore allows the first steps in the area of experimental vibration analysis or modal analysis. Experimental vibration analysis is an indispensible element of modern shipbuilding development activity. This unit allows the natural frequencies and modes of the model ship to be measured and recorded. The simple, stylised ship form simplifies the mathematical resolution of the problem. The model ship and an electrodynamic exciter are attached to a height adjustable cross beam. The beam has a high natural frequency that doesn’t interfere with the measurements. A function generator creates different exciter signals: sinusoidal, triangular and rectangular signals. The frequency, amplitude and offset are adjustable. An acceleration sensor at various points measures the response of the model to the vibrations generated.
