A vertical suction-type wind tunnel that uses smoke trails to demonstrate air flow around differently shaped models, for understanding boundary layers, separation and rotational flow.
Key features
• High quality, vertical wind tunnel that helps students understand air flow around diff erent shaped objects
• Ideal for small group experiments or classroom demonstrations
• Includes smoke generator and lighting to show flow clearly
• Variable air speed
• Includes a set of models
• Additional model set available separately
Description
A vertical, suction-type wind tunnel with smoke visualisation. Allows demonstrations and student investigations into the fl ow of air around a wide variety of diff erently shaped models.
Ideal for small group experiments or classroom demonstrations, the apparatus is fl oor standing. A variable-speed fan mounted on top of the wind tunnel produces the air fl ow through the working section. Air fl ow is vertically upwards.
A smoke generator connects to a comb mounted in the wind tunnel below the working section. Students can move the comb from side to side to aid investigations into the aerodynamic properties of a test model. Smoke is produced by the vapourisation of a high-quality foodgrade oil. A fi lter helps provide uniform air flow. The smoke is non toxic.
The front wall of the working section of the wind tunnel is transparent and removable. This enables users to easily and quickly attach the optional models to the back of the working section. It also allows a clear view of the smoke trails. The wind tunnel includes a set of models, with an additional set available separately (AF80b). Lamps illuminate the working section from both sides to improve the visibility of the smoke.
The wind tunnel is held on a metal frame fi tted with castors for mobility. A control unit on the frame contains the controls for the fan speed.
