Subj: Mouthpiece and reed airflow
Date: Wed, 7 Jan 1998 12:34:43 -0500

The air flow in a dynamic system such as a coupled reed/
mouthpiece system involves some of the hairiest mathematics
around just to do a rough simulation. There is transition from
laminar to turbulent flow as the reed hits and separates from
the mouthpiece, quick airflow reversals due to the pressure wave
returning to the mouthpiece/reed, and boundary conditions
at the baffle and chamber I can just guess at (possible vortex
creation and effective aperture necking - could this have
something to do with apparent resistance?)

I've got access to a 16 node SP2 and 8 processor DEC 8400 -
anyone want to try doing just a preliminary 2d Navier-Stokes?
This could easily be the basis for a Master's thesis.
