'Turbulence' is a technical term that has no relevance to the slow airstream that enters the clarinet – EXCEPT that, if the higher velocities associated with the VIBRATIONS of the aircolumn in forte encounter sharp edges, turbulence can become important. (See Benade.)
Yes, the slow airstream has little direct effect on the resulting sound. A faster airstream is typically associated with a different sound because, to achieve a faster airstream, you need a particular sort of mouthpiece/reed combination. And it is THAT that does affect the sound.
>> It follows then that all the stuff we talk about regarding breathing, support, diaphragm, oppositional forces, etc., boils down to getting the reed to vibrate properly.>>
Or, you could say that all the stuff we talk about reeds, embouchures etc boils down to getting the aircolumn in the clarinet to vibrate 'properly'. (The leakage of this vibration into the environment is what constitutes the the sound of the instrument.)
There is no adequate scientific characterisation of this 'properly'. Everything defers to musical contexts. What is acceptable – even required – in jazz, would not be appropriate to a Mozart symphony.
I wish, however, that you wouldn't ask these questions here. If you do, you get dogmatic answers from ill-informed people therefore ill-equipped to answer them, and you make the BBoard ever more useless to someone trying to find the truth of these matters.
Instead, do a bit of research; say by first reading the excellent website:

...which explains some of the science.
