I've spent hours searching and reading here, and learned a lot already. What I haven't seen much of is a good explanation of the theoretical science behind various designs. For example - what are the flow characteristics of a K vs a cone baffle, and how does that contribute to suppression? And what does the porting or "mouse holes" really do and why/how?
I'm a licensed mechanical engineer that works with gas flow every day (although in MUCH lower temperatures and pressures!), and vaguely remember some of my fluid dynamics classes - but still have my books to refresh my memory. From what I understand though, very little of that applies as the fluid flow is closer to plasma and nothing like an ideal gas.
Is there a primer on suppressor design theory somewhere? Or is it all trial and error?

People talk about Paulson's book a lot.
Synopsis from some threads on the topic ... K's and mouse holes work best for smaller, lower pressure calibers, stick with cones for the big, higher pressure calibers

Here's the issue - I'm trying to understand why and how the above seems to be true, not just if it is true!doubloon wrote: Synopsis from some threads on the topic ... K's and mouse holes work best for smaller, lower pressure calibers, stick with cones for the big, higher pressure calibers
Thanks for the link - that is a good thread, but it's all about the mechanical properties and calculating the pressures and wall thicknesses. That part I have a pretty good grasp on. I may have to get the Paulson book.

Re: Understanding Theory
Near as I can tell its pretty much reading the chicken bones and then applying the proper chant while you pray to the gods of the machine tool.

Re: Understanding Theory
No. My thread is about ideas more than formulae.

I have a few others in the Smithing Section too. And Silencers (Frankford Arsenal report R-1896) is great reading. http://www.dtic.mil/dtic/tr/fulltext/u2/847383.pdf

I'm not ignoring your other thread - it'll just take me awhile to get through it all and be able to comment semi-intelligently. Thank you for posting those!
