“Hey Vertigo glad you like it still. I look at bits as to how I could
improve or better it but everyone seems to really enjoy the spectacle
of it.” paulwayne

How about adding an afterburner cold flame special effect?

Part One

Close to an audience, you might use a cold flame special effect with
just CO2 and a red, orange, or yellow filtered high intensity flood
light inside the afterburner. (Like the hand held search lights with
1,000,000 + candlepower.) The rushing exhaust of cold liquid CO2 as it
changes to a gas and "snow or white translucent and semi-reflective
dry ice solid particles" diffuses the light into a swirling jet of
motion. Deflection tabs can a mounted inside the exhaust nozzle to
refine the shape of the exhaust gas pattern.  Coupled with a recorded
jet exhaust sound effect and it appears very believable.

Best things about the cold flame special effects are no heat or burn
risk to audience, no fire hazard, and no residues left behind like
those from glitter and colored powder injectors.

Note: Touching a cold afterburner nozzle that may be below zero can
cause freeze burns.

Yes, I know you can get glitter and colored powder in bio-degradable
formulations but they can take quite a while to degrade.

Part Two
Why CO2 is the go to gas/solid/liquid for cold flame special effects.

CO2 is normally a gas at room temperature and pressure. It has to be
stored under high pressure to make it a liquid. When you release the
pressure, the gas expands enormously and cools to make a huge white
jet that allows the carbon dioxide gas to expand, cool, and turn into
a mixture of frozen "snow or white translucent and semi-reflective dry
ice particles" and gas.

Basic Science Characteristics of Carbon Dioxide as a Liquid, Gas, or Solid.
Liquid CO2 is produced by compressing and cooling CO2 gas. This liquid
is a clear transparent fluid. Liquid CO2 cannot exist as a liquid at
atmospheric pressure. It must be pressurized above 60.4 psi to remain
as a liquid. At this pressure, Triple Point, CO2 can exist as liquid,
gas and solid. Below this pressure it will flash to a gas and solid.
More specifically, it behaves as a supercritical fluid above its
critical temperature (304.25 K, 31.10 °C, 87.98 °F) and critical
pressure (72.9 atm, 7.39 MPa, 1,071 psi), expanding to fill its
container like a gas but with a density like that of a liquid.

How about adding an afterburner cold flame special effect?

Part Three: Exhaust Nozzle Basics

I received at email asking for information on nozzle designs and how
to prevent freeze up.

The two major problems he referred to are related to allowing the CO2
to exit at high speed, so any snow that forms doesn't block it up and
how to best produce turbulence in the exhaust gas/snow mix.

For many years these were problems with the CO2 fire extinguishers
until they were finally resolved in 1975 by the Brooks Equipment
Company.

Given that their CO2 exhaust nozzle design has not been improved on,
this would appear to be the best place to start when designing a Bat
Vehicle afterburner exhaust cold flame special effect.

If I were building this effect I would start with an intact CO2 fire
extinguisher horn and surround it with three-six small high intensity
lights with a mix of orange, yellow, and red filters.

The mix of colored filters and gas turbulence would give the effect a
pulsing flicker flame effect. One could even set up a pulse flicker
control on the lights themselves. The sophistication and effectiveness
of the afterburner cold flame special effect is only limited by the
user’s imagination.

Carbon dioxide fire extinguishers

3,901,322: Fire Extinguisher Discharge Horn by Jack Winston, Brooks
Equipment Co., Inc., August 26, 1975, courtesy of US Patent and
Trademark Office. Photo-image attached.

The CO2 fire extinguisher horn is designed very carefully to stop two
major potential problems: It allows the CO2 to exit at high speed, so
any snow that forms doesn't block it up, and creates uniform gas/snow
turbulence. This typical design from a patent by Brooks Equipment in
the 1970s solves both problems.

Hi Vertigo thanks for advice and info my friend. I have a mini smoke machine wiŕed to a invertor but most of my shows are during the day so you dont get the benefits of the special effects

I use to use CO2 effects all the time in shows. It is superior to chemfog in may ways. It can be used as a jet under pressure or as a low lying fog when not under pressure. It does not "linger" in the air like chemfog.

There are some concerns as well. In an enclosed space you would need ox sensors because the CO2 could possibly displace enough oxygen to become dangerous. And for the CO2 to be effective there needs to be enough ambient moisture in the air. The white smoke effect is caused by freezing the moisture in the air. There is also the probability of small pieces of ice being propelled from a jet effect.

“Going to look into the co2 after burner cheers guys will keep you

Hey paulwayne,
Will be looking forward to seeing your progress on the co2 afterburner.

I have been thinking about doing one for my Tumbler.
I am leaning towards the idea of mounting a large single high
intensity yellow filtered round light in the center and surrounding
the circumference with mini-nozzles built like the fire extinguisher
nozzle and angled towards the center of the light beam, converging at
ten to twenty feet. Also, adding a few small red filtered high
intensity lights around the circumference with intermittent timers for
a flicker effect.

The cold flame afterburner seems to be limited only by the imagination
and sophistication of the builder’s translational skills into reality.
It appears there is a lot of room for experimentation and execution.

Hi Vertigo your attention to detail never surprises me i just usually plod straight into something with little thought but its worked out so far lol. I had thought about using emergency strobes like i would have on my recovery truck . They are yellow and woyld give the flickering effect with a couple of them mounted together.
