[FrankW]

Anyone know of any thing that will
genearate a smoke stream to indicate
air flow in an electronic enclosure?
TIA

An incense stick.

I've seen these used for checking HVAC air flow, but note the CAUTION about
being corrosive.

The stuff uses for refrigeration is Titanium Tetrachloride...used in
movies...but it will probably be cheaper from a refrigeration parts supply
house.
Its also used in wind tunnels for thin streams of smoke, to show air flow
over surfaces.

This was kind of a cool Amateur Scientist idea:

As cigs are probably illegal or unacceptable in the workplace, the
joss* sticks JL mentioned (from your friendly neighborhood
Indian/Chinese/New Age emporium) could be substituted.

* apparently Pidgin from Portuguse deus (god).

Hello Frank,

Bull Durham hand rolled would be really cowboy style. For longer
episodes and a nicer smell maybe Skandinavik Mixture pipe tobacco.

-----
When Chinese joss sticks are burnt they release significant amounts of
polycyclic aromatic hydrocarbons (PAHs) like butanal and propanal, and of
aldehydes, like formaldehyde and acetaldehyde. These have been linked to
skin inflammation on contact (contact dermatitis), which is a marker for
increased risk of childhood leukaemia, childhood brain tumour and cancer of
the nasal passages and pharynx.

Burning the joss compound wrapped round a bamboo stick releases even higher
levels of these chemicals, demonstrating that bamboo is also a natural
source of PAHs.
-----

A red hot soldering iron dipped in oil (extra virgin olive oil perhaps)
gives
also a nice amount of smoke. Or feeding small amounts of oil through a red
hot metal pipe. I also recall DUT's generating huge amounts of smoke all by
themselves, automagically

For a cheap and cheerful short-term indication, rub some wax on your
soldering iron - but be aware that the heat of the iron may induce some
extra convection.
