| 12 hours ago | comment | added | Michał Kuczyński | Thank you for your answer. I understand now the physical reason for neglecting the convective term. However, it would be preferable for me to show this with a formal argument. perhaps the Navier Cauchy equation could be averaged over the period of the wave oscillation? I think setting $\left<d\mathbf{x}/dt\right>=0$ would be more correct, right? | |
