Wind Tunnel Air Flow Tracer for effective air flow visualisation using a smoke wand
Designed to facilitate the
observation of air movements in many types of flow situations,
primarily in wind tunnels.
The unit is easily transported,
is rapid and simple to set up and use, and produces a controllable,
non hazardous smoke effect.
The smoke is produced by peristaltically
pumping an innocuous, medicinal quality white oil to the
tip of a probe, where a low voltage electrical coil heats
it to produce a dense plume of smoke, at exactly the position
where it is needed.
The special 'smoke wand' probe is shaped to minimise
wake generation, ensuring that the smoke can be entrained
into the airstream smoothly. A stable and clearly defined
plume of smoke can be generated at air speeds up to 90m/sec
(200mph).
