You might try low pressure ambient at the tail if your start condition is high at the intake. All these years, and the one thing i still want to show on a running motor is the alternating nature of intake and exhaust pulses.
We'd always look at the sound file and say "wow, the second mode is REALLY STRONG!" I think i can see it in this video.
Yes I am good and everything is smooth now. Hope everything is fine from your side.
Low pressure at outlet seems good initial condition, I will surely try it in my next simulation. The original initial condition that i gave is velocity of 10m/s all over the domain. The reason to give this was to mimic the blower air velocity inside pulsejet which we usually do in real time.
Now I am actually trying to perform Aero-acoustic analysis to visualize the pressure pulses inside and outside PJ. I thought this might give us an idea of the sound frequency at outlet. One important update, some people told me that we can even export the simulated pressure pulses to audio format and hear it live
. Really excited to move on to acoustic analysis. Once it is done I will surely update it here in forum.
Thanks for following my post.
