波-波间非线性能量传输的一种新计算方法
A new method for exact computation of the wave-wave non-linear energy transfer
-
摘要: 从最基本的Boltzmann六重积分出发,在借鉴其他作者研究经验的基础上,建立起一种新的精确计算模型。该模型不但获得了与前人相一致的结果,还能够清晰的表现出每一个参与相互作用的共振架构对能量传输的贡献大小,并且直观的反映出构成这些架构的共振波数的详细情况。该研究工作为深入研究不同海浪谱中非线性能量传输特征以及其近似计算方法改进提供了基础。Abstract: Based on the original Boltzmann integration, a new model for exact computation of the non-linear energy transfer between wind waves has been set up and its results coincide with the other authors’. The new model also can present the contribution of different configurations to the total energy transfer and the structure of each configuration is illustrated directly and clearly. Advanced studies can be carried out based on this model, such like the study of the structure in most-contribution configurations and the study of improving approximation computation methods.
