I want to accurately simulate the sound of a flute. I mean: the musical instrument.
Is CFD the right field?

How would I start? :-)

The sound of a flute has two aspects. One aspect is the air flowing through the flute. That is an atonal sound, which I want to call "noise". The other aspect is the creation of a standing wave. That is the "musical" part, where the pitch is generated.
In order to really capture the characteristics of a flute, you need to simulate both noise and the pitch generation.
Also transients are important, i.e. the sound is different in the very beginning, when you start blowing, compared to "steady state" solutions, when you have sustained the flow for a while.

I should probably add, that I have a solid background in physics, but I am new to CFD.
