ESOLS Engineering Education Equipment

This ESOLS Flow Visualization (Hele-Shaw) Apparatus used to study various source and sink arrangements, and look at flow around an unlimited variety of different shaped models. This Apparatus can be used to visualize streamline fields for flows around drag bodies and flow through changes in cross-section.

The streamlines are displayed in color by injecting a contrast medium (ink). Sources and sinks are generated via four water connections in the bottom plate. The streamlines can be clearly observed through the glass plate during flow around and flow through. The water flow rate and the quantity of contrast medium injected can be adjusted by valves. The water connections are also activated by valves and can be combined as required. Individual models can be cut out of a rubber plate that is included.

This unit can be operated by Laboratory supply of with any Hydraulic Bench.

ESOLS Climbing and Falling Film Evaporator Plant allows the operating behaviour of a rising and Falling film evaporator to be investigated. The untreated solution is fed from the feed tank below into the evaporator. The evaporator is a double pipe heat exchanger that is heated by steam. The steam pressure on the casing side is adjusted with a PID controller. A cyclone is installed after the evaporator to separate the evaporated solvent and the concentrated solution. The solvent vapour removed is condensed in a water-cooled condenser and collected in a tank. The concentrated solution can also be collected in a tank or fed back into the evaporator for the concentration to be increased further.
