Turbocharger Impeller

[Conceptual]

Can I spin a turbocharger impeller in the opposite direction of a Turbo system, and have it intake air from the edge, and exhaust from the center?

Turbos use the impeller to intake air in the center, and expell from the edge. I am interested in this can be reversed effectively by reversing the rotation.

Any information, as always, is greatly appreciated!

I don't think it would work because it works upon accelerating the air off the tip of the blade.

A new blade design might work - over to someone else for that

A centrifugal compressor draws air in the middle, and expels it at the tips, which usually form into some kind of plenum. The way you describe, you wouldn't get the air to flow properly. You would find that the end that sucks still sucks. And even if you reversed the direction of the impeller, it would still suck. Poorly, but it would.

Not with any kind of efficiency you'd want to use.

Does anyone know what kind of blade draws from the edges, and discharges from the center then? I can model it myself in CATIA, but I wouldnt even know what to reference.

Thanks for the replies so far!

I don't see any kind of blade design making this work.

The thing is, once it rotates, it will push anything around the rotor outside. Any atempt to make it push toward the axis is rowing upstream.

Why exactly you need it working that way? You can have an axial flow compessor (jet aircraft alike).

[Scotracer]

A Turbo-supercharger works through the principle of centripetal acceleration of the fluid (and its own inertia) increasing the velocity of the fluid. You would lose all of that gain by making it work in the other direction -- a futile endeavor.

Looking forward to your Tesla turbine/turbocharger prototype your building this Summer.

Most helicopter turbines combine radial flow turbine & compressor, you could try a similar arrangement:

Funny that you should mention that, since it was during the research on that project that I stumbled over something Mr. Tesla started, but never finished, and since he stated that the gizmo's purpose was the last item needed to make a flying car, I wanted to see if I could see where it needed to go in order to work.

It doesnt look too complicated, but it requires a blade that draws from the edges, and discharges out the axis.

Maybe thats why he never finished it?

Very good, but I cannot tell if the blade intakes from the radius, and exhausts out the axis. I did send an email asking that exact question, so here is hoping!

are you looking for a ducted fan they basically pull air from the edges of he duct and force it out the center. Also Tesla kinda went crazy in his later years

That is because when you use your brain to build CATIA-like 3D shapes, and then you load and run the CFD simulation, your brain overheats, and starts to deteriorate. I think that is what Mr. Tesla did, he just melted from trying to solve these equasions without computers. Its like the black hole that sucks you in until you pop.

Much like a Salvia trip, I might add...

Anyways, a ducted fan would work, but I am contemplating if it would be worth the added weight of having a cone that creates a seamless surface for the air to travel down to reach the ducted fan.

Maybe I'll sketch one tonight, and upload it so I can show you what I mean.
