发帖数: 30 | 1 I guess what the chemist and physicit could do is
just to control the difussivity D, as the D has
reflected all of chemistry and physics(not mechanics).
If we assume the N-S euqation is still applicalbe here,
the diffusion is proportinal to 1/(Re*Sc), Re=U.L/mu,
Sc=mu/D,
U, L :velocity and lengh scale respectively, mu, viscosity.
So we could enlarge the U, or L to reduce the diffusion as
well.
But maybe you don't like it.
So I suggest another wholly mechanical way(just rough
suggestion):
