Applied hydromechanics, Vol. 12 (84) ¹ 2, (2010) |
| Small (linear) oscillations of ideal fluid in partially filled vessel with rigid perforated bafflers are considered. The mathematical statement of the problem with averaged conjugation conditions on the bafflers is given in assumption of large number of perforating holes. Variational statement of the averaged normal mode problem is given as well. Some general properties of eigenfrequency spectrum are found. Several examples are considered. |
