| 摘 要： | 1. INTRODUCTIONIt is well known that in a closed basin or in a harbor with a narrow entrance, resonance will occur when the external exciting frequencies are close to the standing wave frequenies in the harbor. Near the resonant frequency, a relative weak…

| Abstract: | A narrow open channel resonant phenomenon, newly found by the authors in corresponding numerical calculations, was proved to exist based on the method of matching asymptotic expansions for three different channel configurations. It is shown that the resonant wave number k emerges around kL=nπ, n=1,2,3,…∞ with a corresponding frequency shift, where L is the length of the channel. It is also clear that the resonance in a narrow open channel is an essential property of a channel as long as it is uniformly narrow. |
