smoke anyone?
Archiver
Posts: 46,084
I'm working on a little project that controls a finned air heater with a
stamp. My need is a little OT, but this group seems to have someone for
everything. I want to blow air across my heater with a visible indicator of
the airflow - so I can maximize the amount of air over the heater. I thought
of making some colored smoke in the way it's done for wind tunnell testing.
Does anyone know how to safely generate this kind of smoke?

Depending on the rate of air movement, perhaps you could use large incense
sticks or cones?
They're cheap, burn a long time, provide quite a bit of smoke, and make
the room smell pretty! *laugh*

higher now - 40 to 100 cfm. Actually, your idea works well for checking
suction from free air.
There is software available to simulate this effect also, but it's super
costly.

LOADS of smoke for about 30 seconds, depending on size.

Ah...I wasn't sure what your volume was...for small projects this works

You could use dry ice, or rent a smoke machine from a magic / costume shop.

Do you need to view the actual path of airflow, or just need assurance that
air is indeed flowing? If the latter, small bits of crepe paper or yarn will
"wave in the breeze" quite nicely and indicate direction as well. I've seen
this technique used in wind tunnels and water channel testing. Perhaps by
careful placement of a photo interrupter, a signal could be provided to the
Stamp, to let it know all is well.

I make single to three phase converters. See:

or

effects? What I mean is maybe to use small plastic strips or ribbons
that will indicate the direction and velocity(somewhat) of the air?

it by hanging it out the car window.
...Or a small hobby propeller connected to a small motor -- max flow = max
voltage generated by motor.

all kinds of neat colors. Theatrical shops shold have something.
You can even cut them into smaller pieces for less smoke or shorter
tests.
Forget CO2, or dry ice, it'll dissapate when it moves fast unless
you're only blowing the 'fog'
