PRODUCT OF WIND TUNNEL

Make a big wind tunnel

A honeycomb structure

This is made for a plastic board which is a beehive-shaped hexagon and thin. In this case, I used a honeycomb structure which size is 90cm × 90cm and a depth of 5cm. (Ordering to a professional trader) The flow of air is rectified by this, and a laminar flow runs into a wind structure.

make a nozzle

Make a hole (5mm) in a brazen pipe which inside diameter is 1cm, and set up a thin nozzle (5cm) by soldering. It is easy to put a solder by small burner.


Emit smoke

Set up a nozzle, and emit smoke. I use a fog liquid. This liquid which is high viscosity is emitted fog-shaped for high temperature. It is seen well than incense burning and dry ice.

Complete a nozzle and a smoke tank

Save the smoke from smoke generator in tank, and it is emitted from nozzle. Tank is connected a metal funnel and a can of a mosquito coil.


Inside of wind tunnel

It is seen a honeycomb structure and a factory fan. There are a smoke nozzle in the center and an observation window made for clear plastic in right side.



Smoke generator

Another name are smoke machine and fog machine. It can be bought for \4000.



Make a small easy wind tunnel

A laser beam amplitude equipment

Combine a laser pointer and a toothbrush, and be reflected. The light is devoted, and point to a radiation object.


See the flow of air around wing

A light from a laser beam amplitude equipment point to around a wing of small wind tunnel. A funnel on under side emits smoke, so it is seen to the flow of air around wing.

Make a super small easy wind tunnel

This is A3 size, so carrying is easy!

This is smaller than small wind tunnel and A3 size. There is a smoke tank under nozzle, Inhale and discharge air by fan.
