6ms...still filling the cc.
Slowing down out of the augmentor... but still flowing!

A simple experiment to try

CC has hit atm again, still flowing out the back of the augmentor...
Apparently its mixing up in the cc with some still fairly hot gas.
one more... i promise only 1 more.

Big, fast, broke, fix it, bigger, better, faster...

[/url]Awesome vortex!
Rossco,
That is amazing stuff.
The reason that I suspect that a CFD program wouldn't show any Ranque effect (if it's even present) is because I think that the slight viscosity in the gas is what causes the synchronization of the helical flow in a Ranque tube. Most CFD programs use the inviscid version of the Navier Stokes equations (Euler's equation), so the physics that cause the effect are not part of the simulation.
Your simulations make me suspect that the vortex probably doesn't last long enough for the flow to synchronize.

DONE! time for me and my puter to have a rest!
8ms and it came to peak pressure in the CC again of 15.2175 psi.
The time all seems a bit off to me?
That was the longest 8ms of my life!!!!
There is still flow out of the augmentor...
Pez, ill have to look into that detail... couldnt say one way or the other just now. Sorry i compleatly hijacked your thread, i just got on a roll, so to speak. Ask Mike, and im sure he will split it off for us if you would like to.
Ah well, there you go... now, what did we learn? dunno, ill have to go think about it all now. I sort of wish that i did a proper engine and proven augmentor now...

I wish every post that I made got hijacked that way.
I have never understood why people get irked if a thread goes off in some unexpected direction. That's the whole point of interacting with other people on a forum - collective knowledge, collective creativity etc.
At any rate, I definitely learned a lot about augmenters based on your posts.
Thanks!
