Stability models of rocket engines 1

[Lumbisno]

Hi everyone! hope you are all doing well, I was wondering where might I find solid info of how to build a mathematical model of stability in a rocket engine (given certain known parameters).
Thank you all in advance!

I'm pretty sure I've seen this question before, and the answer is that it is cutting edge simulation, and/or experimentation.

Cheers

Wow, the exact same question. Are you a bot, Lumbisno?

So, 2 months later, you've made no progress? If anything, there's signs of regression, since your original question had more detail.

TTFN (ta ta for now)
I can do absolutely anything. I'm an expert!

Just so there is a little context, in between these two months i have been taking all the end of year exams and I am now returning to this project, did not intend this question to be interpreted the same way as my previous one, instead, i'm now looking into how to start building a good representation model of a given system, as opposed of the analythical generalisation (which is frankly impossible for my level at least) of said systems, I do want to make clear that I'm a beginner in this field and that's why maybe these questions seem weird, for the next one I intend to be more concrete, thank you all

So you search google using the obvious terms, you read some of the many papers, you pick one that seems to have about the right level of detail, and study that.
