Improvised or homemade .22 suppressors

The place for beginners, or anyone else, to talk about gun, gear, and shooting topics with a minimum of jargon and/or geekery. The only stupid question is the one you don't ask that blows up in your face later.

Apparently, nobody has come up with a good math model yet. The fluid dynamics are VERY complicated, as you are talking about highly turbulent flow, substantial heat transfers, and all of it in the boundary layer.

As I've said, it's a doctoral thesis. And not a simple one, either.

I can believe that. Some years ago a friend of mine took a problem to the CFD guys at the aero engine division of Rolls Royce ( my friend worked there too, as an engineer )
The problem was to simulate the airflow in the transfer port of a spring piston air rifle, with a view to establishing an optimum shape.
The CFD guys did some initial calculations and told my friend that they didn't have any existing code which was suitable and creating some would be a huge project, so they couldn't help.
