Applied hydromechanics, Vol. 15 (87) ¹ 2, (2013) |
| Employing the secondary (internal) resonance condition for steady-state sloshing in a conical tank that appears due to resonant excitation of the lowest natural frequency, the paper establishes a set of input geometric parameters (semi-apex angle and liquid depth) for which the secondary resonance phenomenon can lead to amplification of higher modes. A series of recommendation regarding the forthcoming development of nonlinear modal methods for the indicated tank shape are formulated. |
