EXPERIMENTAL STUDY ON AMPLITUDE FREQUENCY MODULATION CHARACTERISTICS OF ROGUE WAVES

  • Generating rogue waves in offshore tank during the scaled model tests of an offshore wind turbine is very important, and the generation mechanism and generation probability of rogue waves have always been a hot issue in the research. Therefore, through the experiment in the ocean engineering experimental tank, the experiment uses the random amplitude and random phase method to generate the initial wave sequence, and makes a statistical analysis of the experimental results. The wave energy spectrum is studied to explore the evolution of waves and the probability of rogue waves. The results show that in the wave propagation, the spectral peak moves down and the frequency of the spectral peak decreases gradually. The wave height distribution of waves does not obey the Rayleigh distribution, and the wave field with large BFI is more prone to limit wave height or rogue wave.
