HM 132 Vertical visualisation of flow fields
Fine gas bubbles are perfectly suited to visualising flow fields. Due to Reynolds scaling, many flow processes that occur in air can also be demonstrated by experiments in water.
The trainer consists of a vertical experimental section in which an interchangeable model is inserted. Water flows from bottom to top through the experimental section. Electrolytically generated hydrogen bubbles rise with the flow, flow around the model and visualise the flow. Different models are available: drag bodies (e.g. aerofoils and cylinders) or changes in cross-sections. The length of the experimental section enables for a long wake, where, for example, vortex streets form completely. The black background and the lateral illumination ensure optimal observation. The model can be inserted in two different positions.
CE 610 Comparison of Rectification Columns
The rectification columns are used for the separation of liquid phases. They operate according to the principle of distillation. Distillation is a separation process that includes the partial evaporation of a liquid phase and the condensation of the resulting gas phase. The separation process of rectification is an energy-efficient distillation process with several stages. The substance mix recommended for the operation of the experimental plant is water-ethanol. The CE 610 experimental plant is designed for the continuous operation of one rectification column at a time. The rectification columns are a packed column with pall rings and a sieve tray column with ten trays.
Exhibitions / Trade fairs
14. - 18. February 2017: didacta - The trade fair for education and training
didacta - the trade fair for education and training is held in Stuttgart every three years, alternating with Hannover and Cologne. As Europe’s biggest trade fair for education and training it provides in-depth information on the entire education and training system, from early childhood education and vocational training through to lifelong learning. A first-class further education programme for teachers, educators, trainers and educational staff complements the offering of this varied event.
You are welcome to visit us at the trade fair in Stuttgart at exhibition booth B64 in hall 6 .
