| Abstract: | In this paper,we study the characteristics of the chaos in a driven square cavity by applying a consistent fourth-order compact finite difference scheme recently developed by us.By means of chaotic time series analysis,quantitative study of the flow system in the square cavity driven by the higher of Re.From steady state to chaotic state,the chaotic characteristics are given in detail. |
