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.

Re: Improvised or homemade .22 suppressors
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 )Mike OTDP wrote:Apparently, nobody has come up with a good math model yet.
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.
