Abstract

The invention relates to the technical field of the physical oceanography and discloses a method for simulating freak waves under the fractal sea surface background. The method comprises setting sea surface parameters and freak wave generating positions and moments; calculating the wave rising height of the one-dimensional fractal sea surface according to fractal parameters; using a phase modulation method for generating the freak waves at specific positions and moments; adding the wave rising heights of the fractal sea surface and the freak waves to obtain the wave rising height of the freak waves under the fractal sea surface background; and calculating characteristics of the freak waves under the fractal sea surface background. According to the method for simulating freak waves, non-linear factors in sea waves are considered, the freak waves with different geometrical characteristics can be simulated, and the calculation efficiency is high.

Description

technical field [0001] The invention relates to the technical field of physical oceanography, in particular to a method for simulating deformed waves under the background of fractal sea surfaces. Background technique [0002] The deformed wave has the characteristics of extremely high wave height and sharp and thin crest. It poses a greater threat to the safety of offshore oil platforms, coastal engineering and shipping. Due to the short duration of the freak wave in the sea surface, the actual observed data of the freak wave is less. At present, numerical simulation and laboratory physical simulation are important means to study deformed waves. [0003] The mechanism of deformed waves is the premise and foundation of simulating the deformed waves. It is currently recognized that there are several reasons for the generation of deformed waves: the interaction between waves and currents, the modulation instability of nonlinear waves, and the space-time self-focusing of mult...
