CML Models and the Nonlinearity of Turbulence

Department of Sediment, China Institute of Water Resources and Hydropower Research, Beijing 100044, P.R. China

摘要: 本文在现有耦合映射格点(CML)动力系统模型的基础上,提出了能够同时模拟对流项和扩散项的强弱耦合系统的CML模型,分析了这类模型的特点和结构.数值试验表明,这类CML模型能够有效地研究时空复杂性,利用数值模拟的结果对湍流的物理机制作了初步的阐释.

Abstract: Some new coupled map lattice (CML) models are developed for simulating both convection,diffusion terms and weakly or strongly coupled terms.The structure and features of model are analysed.Numerical results show that the new models are effective for studying spatiotemporal chaos.Finally,the of mechanism turbulence is analysed via the numerical results.
