How can I theoretically determine the effect of acoustic perturbations on laminar-turbulent transition in a heat plume (i.e. rising smoke)?

I've done some preliminary reading on how Tollmien-Schlichting waves play a part in these perturbations, but is there a formula that connects sound frequency with the transition stage?...

Is there anything quantum mechanical related to Fusion/Fission? ( Instead of special relativity)

Fusion/Fission is always accompanied by the special relativity relationship of $E=mc^2$.Yet there are atoms that are undergoing change, and that should be in the realm of Quantum Mechanics....
