Hydraulic engineering experimental facilities

Within the framework of a laboratory cooperation within the Department of Civil Engineering of the UDE, the laboratories of the Institute work in association with the laboratories of the Departments of Geotechnical Engineering (Univ.-Prof. Dr.-Ing. E. Perau) and Urban Water and Waste Management (Univ.-Prof. Dr.-Ing. R. Widmann). This cooperation results in an efficient and comprehensive access to a wealth of high-quality laboratory analysis methods for water-related questions in the fields of hydraulic engineering, geotechnics and water pollution control for our research activities and clients.

In the laboratory of the Institute of Hydraulic Engineering and Water Resources Management of the University of Duisburg-Essen, research and development is carried out in addition to teaching and training for students. For this purpose, premises of the hydraulic engineering laboratory are divided into an approx. 120 m² teaching laboratory, as part of a larger laboratory hall on the second floor within the building bridge V15. The area of the research laboratory is located in an experimental hall on two levels with a total floor space of approx. 480 m² and 10 m height.

Teaching Lab

The teaching laboratory is used for practical courses to train students. For this purpose, a 2.50 m long teaching flume specially created in the university's workshops is available, as well as some teaching units from the company GUNT Hamburg.

The flume is used in practical courses to illustrate flows and flow conditions in an open flume. There is a closed water circuit in the flume and the gradient can be continuously adjusted. The following fixtures for the flume are available:

Weir
Weirs (WES profile, sharp-edged, wide-crowned)
Bottom sill
Segment weir
stilling basin
Wave generator

Modules of the company Gunt Hamburg are operated on a base unit, which can be equipped with any number of units:

Theorem of Bernoulli
Francis turbine
Pelton turbine
Centrifugal pumps
Flow measurement
Hydrostatic pressure in liquids
Measurement of jet forces
Flow conditions in pipelines (Osbourne-Reynolds)
Flow over weirs
Loss detection in bends and pipelines

Experimental hall

Research takes place in an approx. 480 m² experimental hall shared with the Department of Urban Water and Waste Management.

In the designated area, experiments for research work can be individually created and carried out. For these experiments as well as for field work, measuring equipment for e.g. flow velocity, pressure, water levels, terrain conditions is available (measuring equipment hydraulic engineering laboratory).

The water supply for the hydraulic engineering tests is provided by 3 low-pressure centrifugal pumps with a total output of up to 55 kW and a maximum flow rate of approx. 360 l/s. The service water is drawn from a storage tank with a volume of 80 m³ and is usually recirculated.

Currently, as part of a PhD, force, flow velocity, and water level measurements are being measured on cylindrical bodies to gain insight into the hydraulics of dead wood in streams.
