function of a swirler

[mael]

Hello everyboy is this how a swirler work ?

That's definitely one way to do it, but this is a hobby forum and you're not likely to find much help with liquid rocket engines here.

My first thought was that this is a new toilet design.

Thanks a lot can you advice me a more appropriate place ?

my question is that : does the hot gas could transform the liquide into a gas to, at the end of the swirler's nozzle

There are multiple problems with this A: Swirl injectors only work with liquid prepollents B: Your injector is going to blow up because you are using gaseous hydrogen C: You are going to get poor atomization of the propellant's even if you used a liquid oxidizer and fuel To answer your question no because you wont have an injector. Assuming that it would work with out blowing up, that is not the point of a swirl injector. The point of a swirl injector is to A: get the propellant's into the combustion chamber B: To atomize the fuel and oxidizer to get symmetric burning. Why are you wanting to know this??? It seams like you have done no research or even read a relevant textbook like Rocket Propulsion Elements. You should also gain access to the research forum if you are wanting to talk to people doing similar things.

The fact is that I heard that swirlers were used for mixing gas and liquid. But every draw I saw only shaw liquid injection, like the famous coaxial swirler injector of the copenhagen suborbital that only mix liquid (I think).
What will create the explosion ?
And my idea was to maximize the atomisation. Just an idea from a student that have a lot to learn.
Thank yoou for thebook advice and for the forum too.

Thanks for your message.
How could I gain access to the research forum ?

How could I gain access to the research forum ?

It requires having a NAR or TRA Level 2 high power rocketry certification, and requires being a "US person" under the ITAR law, i.e. being a US citizen or legal permanent resident (green card holder). So, guessing by your English in the several posts above, you probably can't.

I'd second @SpaceX76's suggestion that a text book is a much better source than a hobby forum. Also, you might try a nearby university, as effective liquid bipropellant propulsion is a very advanced topic that one is unlikely to master on one's own, and certainly can't from a single book.
