| Abstract | In order to eliminate the unwillingly generated parasitic waves form the resulted wave profiles, a 2nd order wave generation technique is essential to carry out correct model test in the wave basin. These so-called parasitic waves cause an amplification of long wave phenomena, such as harbour resonance and oscillations of moored ships. These parasitic waves can be eliminated by means of compensating free waves imposed on the system by second-order paddle motion reproducing the natural set-down. The control signal for this motion has to be introduced along with the primary waves. The code SPWNW is utilized to serve the above purposes. In the present experimental work we have employed 2nd order wave generation technique to generate regular wave in the OEB basin. Measured surface elevations at different locations in the wave basin for each case we considered here are compared to check the wave propagation in the basin. Later the relevant surface elevations measured for both the 1st order and 2nd order wave generation technique and those predicted by the SPWNW code are compared and presented in this report. |
