Newly discovered ‘blue whirl’ fire tornado burns cleaner for reduced emissions
Researchers say their discovery of a type of fire tornado they call a ‘blue whirl’ could lead to beneficial new approaches for reduced carbon emissions and improved oil spill cleanup.

I can’t see how it would work
i don’t think you want swirls in a combustion chamber, the fuel droplets would be more likely to collide than spread out
electrostatic fuel distribution would be better where it slightly charged as its pumped through the injector would be better i reckon, the charged droplets would repel each other creating a finer mist?

actually, swirling in the cylinders leads to a more efficient motor..
but motors need explosive combustion, not a continual flame
and you are decades too late with the electrostatics Mr Brock…
The thread title “Newly discovered blue whirl burns cleaner” looks like it was made by a random word generator.
And it is hazardous to the help…
Swirl jet combustion has been around for 100 years or more.
> The Clark School team initially set out to investigate the combustion and burning dynamics of fire whirls on water.
But this strategy may be new.
> Some oil spill remediation techniques include corralling up the crude oil to create a thick layer on the water surface that can be burned in place, but the resulting combustion is smoky, inefficient, and incomplete.
Sure can, sure is. Burning crude oil in spills turns not-so-bad water pollution into much-worse air pollution.
> their discovery of the ‘blue swirl’ can serve as a natural research platform for the future study of vortices and vortex breakdown in fluid mechanics.
I’ve done some study of the fluid mechanics of vortices in my own work, in which a fan in a tube generated a tornado-like vortex all the way down along the tube to the flat bottom. The bog-standard mathematical model of turbulence fails spectacularly for such flows, more advanced turbulence models do much better. Another thing I found was that I could easily control the diameter of the eye of what was effectively a tornado by a simple change in fan design. But where the tornado actually touched down turned out to be unstable.
I didn’t work directly with vortex breakdown, but a colleague of mine is a world expert.
On one of Richard Hammonds shows they made fire tornados on demand by setting an L shaped fire. Didn’t specify in which direction to the prevailing breeze but they could made them on demand and only took seconds for the tornado to take shape.

mixing’s good

the most effective and easiest way of improving fuel economy is making a vehicle lighter and decreasing drag , the way the air moved and under the vehicle is important , the air flow under a vehicle is turbulent because of the components shoved under out of sight , apparently the way air moves around the tyres is important

Good comment! I’d forgotten about that. You’re absolutely right.
I had been thinking that inducing swirl in a fire of crude oil in the open ocean would require a lot of expensive heavy mechanical equipment.

Could a large spinning fan do the same thing?

I have seen bushfires create their own fire swirl. Some reach 30 metres high & are intensely hot.
assange might put a torpedo into the clinton campaign a few weeks from the election or work out a deal from hillary to get him released
you could heat the petrol as its injected i guess so it vapourises easily
you could use the waste heat from the engine to pressurise the A/C system and use a solar array on the roof to help power the A/C system
The condenser efficiency is greatly improved by preheating the refrigerant.

so
make the vehicle lighter
use waste heat to help power the air con
make the underside of the vehicle slip streamed
making the vehicle lighter will yield more fuel savings than mucking around with the engine
