  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.

  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.

  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.

  Modular Flow Channel / 300 x 450 mm

  The modular flow channel 5m working section is a basic unit with a modular construction, which allows the study of flow behavior in a large number of experiments. The extensive accessories give researchers and instructors the opportunity to carry out experiments from all areas of hydromechanics. The measurement section of the basic unit is 5m long. It can be extended by adding 2.5m intermediate sections to reach a maximum length of 15m. Important components of the basic unit are the specially designed inlet area which creates a homogeneous flow, a centrifugal pump for creating the water circuit, regulating flaps for adjusting the throughput quantity, a magnetic-inductive flow meter and a hand-operated slope adjustment which is used to compensate flow losses or to simulate a natural slope. Because the unit can be set up anywhere, its adaptability to specific local conditions is guaranteed. Once the flow channel has been filled it can be operated independent of the water network. The modular construction permits quick and easy assembly at the desired set-up location. The side panels are made of hardened glass to permit a virtually unobstructed view. The measurement section is provided with a guide rail for installing a measuring cart. The inlet, outlet and tanks are made of lightweight GRP to ensure a high degree of stability and a long service life. The separation of channel and support structure ensures the precise alignment of the operating area. The wide selection of accessories greatly enhances the usefulness of the basic unit.
