Abstract

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.
- CML model,
- spatiotemporal chaos,
- turbulence
