CONVECTIVE COUPLED MAP FOR SIMULATING SPATIOTEMPORAL CHAOS IN FLOWS

A coupled map lattices with convective nonlinearity or, for short, Con vective Coupled Map (CCM) is proposed in this paper to simulate spatio temporal chaos in fluid hows. It is found that the parameter region of spatiotemporal chaos can be determined by the maximal Liapunov expone nt of its complexity time series. This simple model implies a similar physical mechanism for turbulence such that the route to spatiotempora l chaos in fluid hows can be envisaged.
