a***n 发帖数: 578 | 1 J = sum ( v * h)
h is hamiltonian, considering ideal gas.
h = p^2/2m.
therefore, J = sum (v * p^2/2m) = k * v^3
J the thermal current. v is velocity. k is some constant. | F****y 发帖数: 145 | 2 Do you have any idea about heat transfer?
Nu=kRe^nPr^m
Re: Reynold number
Pr: Prandtle number
m: ~0.3
n: ~? sorry, I forget, but you can find this equation at any level heat
