AFF100 Wind Tunnel For Visualisation Of Streamlines Vocational Education Equipment For School Lab Fluids Engineering Experiment Equipment
Description
Streamlines can be visualised in steady flow in the wind tunnel by using fog, smoke or tufts. In this way, a clear impression of an instantaneous flow field can be presented and problematic flow areas, such as stall, can be shown.
The experimental unit AFF100 is an open wind tunnel, in which streamlines, flow separation and turbulence can be made visible by using fog. Fog is generated by evaporating a glycol mixture in the fog generator. The evaporated fog fluid is nontoxic, water soluble and the precipitate does not affect common materials. Precipitates can be easily wiped off with a cloth.
The air flow is generated by a fan. To achieve a lowturbulence flow, the air flows through a stabilisation chamber with a flow straightener. Fog is added to the flowing air through several nozzles. Then the air flows around or through a model in a experimental section and the flow field becomes visible. The experimental section has a black background and a sight window; additional lighting makes the streamlines clearly visible.
Four interchangeable models (cylinder, orifice plate, aerofoil and guide vane profile) are included. The aerofoil’s angle of attack is adjustable.
