Fine gas bubbles are perfectly suited to visualising flow fields. Due to analogies, many flow processes that occur in air can also be demonstrated by experiments in water.
Product Features
- Vertical experimental section with interchangeable models for flow visualisation
- Water flows from bottom to top through the section, carrying electrolytically generated hydrogen bubbles
- Models available include drag bodies such as aerofoils, cylinders, and cross-section changes
- Experimental section length allows formation of long wakes and vortex streets
- Black background and lateral illumination for optimal flow observation
- Model insertion in two different positions for varied flow analysis
- Stabilisation tank with flow straightener for low-turbulence flow
- Low flow velocity adjustable by valve for clear flow separation and vortex formation
- Hydrogen bubbles generated electrolytically with platinum wire cathode and frame anode
- Adjustable cathode current with pulse and pause duration control
- Digital display of cathode current and flow velocity on switch cabinet
- Compatible with image processing evaluation methods like particle image velocimetry using special cameras and software
Benefits
- Enables clear visualisation of complex flow fields and vortex dynamics
