动力学级联产生作为Benjamin-Feir不稳定性的基本机制
Dynamical cascade generation as basic mechanism of Benjamin-Feir instability
摘要:
提出了一种新的Benjamin-Feir不稳定性能量级联离散模型。直接和逆级联的出现条件明确给出,以及由于级联终止波系统的稳定条件。这些结果可以直接用于解释实验室实验的可用结果,并作为计划实验的基本预测方案,取决于初始激发模式的频率和其振幅的陡度。
英文摘要:
A novel model of discretized energy cascade generated by Benjamin-Feir instability is presented. Conditions for appearance of direct and inverse cascades are given explicitly, as well as conditions for stabilization of the wave system due to cascade termination. These results can be used directly for explanation of available results of laboratory experiments and as basic forecast scenarios for planned experiments, depending on the frequency of an initially excited mode and steepness of its amplitude.
