Accessories for 32448 Aerodynamics Trainer

Streamlines can be visualized in steady ?ow in the wind tunnel by using fog, smoke or tufts. In this way, a clear impression of an instantaneous ?ow ?eld ?ow can be presented and problematic ?ow areas, such as stall, can be shown.
Visualization of Streamlines Attachment 32448VS experimental unit - used in the 32448 Aerodynamics Trainer - allows the streamlines to be visualized using fog. In the fog generator supplied a fog ?uid is evaporated and inlet into the wind tunnel via a slotted pipe. A model (aero-foil, cylinder, ori?ce plate) is located in the measuring section, around and through which the fog ?ows. The ?ow course for the ?ow around and through becomes visible, as does ?ow separation.
The measuring section has a black background and a transparent front plate for better observation of the streamlines. The aerofoil model's angle of attack is adjustable. The fog ?uid is non-toxic, water soluble and the precipitate does not a?ect common materials. Precipitates can be easily wiped o? with a cloth.
The experimental unit is attached to the air outlet of the 32448 trainer, simply and precisely with quick release fasteners.
The well-structured instructional material sets out the fundamentals and provides a step-by-step guide through the experiments.
