| Résumé | In this work first order and second order wave generation techniques are utilized to study the correct generation of mono and bichromatic waves in the OEB. For a flat bottom wave basin when the interaction between two frequencies are considered bounded sub harmonics or bounded low frequency waves are generated at the difference frequency and bounded super harmonics or bounded high frequency waves are generated at the sum frequency and they travel locked with their generating / fundamental wave components along with some unwanted free waves. These free waves are, free waves due to first order motion of the wave boards, free wave due to displacement of the wave board from its zero position and free wave due to local disturbances. These unwanted free waves are inevitable due to the linear motion of the wave maker. The second order wave generation technique includes second order board motion and correction components of the above-mentioned unwanted free waves. In this study only sub-harmonics or low frequency wave components are considered. Total 14 wave probes are used to capture the data in the wave tank. A NRC-IOT code (LWAVE) is used to isolate the primary waves, the bounded waves and the unwanted free waves from the measured data at each wave probe. The measured data are analyzed in this paper to illustrate the differences in the waves generated by two different generation techniques. |
