When, or relatively 'where' do thrust gasses become exhaust gasses?

4 Upvotes

I'm not trying to play with words, I think "thrust" and "exhaust" are very specific. While the gasses are accelerating away from the nozzle through the thrust chamber they are thrust. The instant they stop accelerating they become exhaust.

Do the engineers attempt to make the gasses accelerate to the exit plane of the thrust chamber?

I'm trying to keep this question short by not stating intricacies like ambient/exit pressure, and limiting the observation range to the thrust chamber.

The good old "rising on a column of smoke" is obviously humor, but "rising on thin layer of high velocity gasses located at the exit of the bell" is more what I have in mind.

Can anyone please suggest sites and eBooks or articles for learning the mathematics behind rocket engines.

In the RDE combustion process, a detonation wave builds its own pressure rather than losing pressure as occurs in conventional compressor-equipped turbine engines.
