Interesting suggestion.Generally, elevated temperature decrease the detonation effect. But I would say that's highly dependent on local conditions.What I could say is that flame propagation is highly dependent on the momentum of particles. With combustion gases, you'll have different species (unburned fuel, different ratio of combusted gases and then air) competing to rush around the compression part of the RDE and react differently to the addition of fuel. That would result in a stratified mix upstream of the detonation and probably a poor variation of pressure overall, very difficult to make stable and homogeneous in the RD part.A quick search brings me this, which I don't have full access:[URL unfurl="true"]https://journals.aps.org/prfluids/abstract/10.1103/PhysRevFluids.9.083202[/URL]
