Outline
There is a strong coherence between random wind and wave environment elements, which not only affects the synchronization and intensities of fluctuating wind and random wave in combined wind-wave propagation process, and but also affects the accurate calculations of combined wind-wave action on offshore structures. Therefore, based on the CFD numerical simulation methods of random wave and fluctuating wind fields, a numerical flume for simulations of combined wind-wave propagation was established, then a series of numerical simulations of combined propagation of fluctuating wind and random wave were carried out. Based on the analysis of numerical results, the influences of wind speed position height, significant wave height, wave peak frequency and basic wind speed on the coherence between wind and wave were explored. According to the influence characteristics of these factors, a calculation function model of wind-wave coherence value of combined wind-wave propagation was proposed. Then, the parameters of the coherence function model were determined by a series of numerical fits according to the numerical results under various influencing factors. Based on this, a concrete calculation expression describing the coherence value of combined wind-wave propagation was established.
