Not sure if we’re talking about cold flow tests here or possible cooling of hot
chambers, but vortex swirling of oxygen was another method utilised by hybrid
researchers to significantly increase the regression rates of polymer fuels.

Orbiter uses a vortex flow of LOX injected at the throat, moving upwards into
the chamber for cooling. I stand to be corrected but I believe that I have read
more than once that this method of cooling was also demsytated by them with a
plastic see through chamber. I also remember seeing a picture of it.
Their original patent I believe runs out in 2018, so this has been around a
long time. I saw the pics in a presentation in 2003.

Prototyping your engine with 3d printed plastic could possibly be
handy for checking fit of components or testing out your gimbaling

Or testing flow patterns under "cold-flow" conditions.
