Stagnation-Point-Reverse-Flow combustor

[MintJulep]

Anyone else seen this?

My initial thought is that it appears to rely on buoyant forces, and that if you start trying to suck useful heat out of the cylinder walls, they will change.

Mint,

Yes I saw it too. Heat extraction (e.g. turbine) would have to be located downstream somewhere, and the walls kept insulated. I don't remember if the article discussed the flow rate range for the combustor, either, and I would imagine it's a fairly narrow one. Good for ground power generation, not much good for motive power (throttling).
