DESCRIPTION

Technical Description

Hydraulic engineering is an important part of technology. How do you establish the required depth of water for ships? How does open channel flow change during high-water? How far upstream do control structures affect the flow? How do you calculate the discharge at barrages or dams? Experimentals flumes in laboratories enable to teach the fundamentals required to understand the answers to these questions and to develop possible solutions.

The experimental flume HM 163 has a cross-section of 309x450mm and includes a closed water circuit. The length of the experimental section is between 5m and 12,5m when using additional extension elements HM 163.10. The side walls of the experimental sections are made from hardened glass allowing optimal observation of the experiments. All components in contact with water are made of corrosion resistant materials (stainless steel, glass fiber reinforced plastic). The inlet element is designed in a way to ensure low turbulent flow inlet into the experimental section.  

The experimental flume can be inclined continously to simulate a slope and to establish a uniform flow with constant discharge depth.

A large varietey of models, i.e. weirs, pillars, flow-measuring flumes or a wave generator, are available as accessories and enable an extensive range of experiments. Most of these models are screwed quickly and safely to the bottom of the experimental section.

The well-structured instructional material sets out the fundamentals and provides a step-by-step guide through the experiments.
