Application of DRP scheme solving for rotating disk-driven cavity

This paper is to explore when the rotating disk-driven cube container structure flow generated by different Reynolds numbers to observe structural reasons and swirl flow field generated in the space discretization dispersion-relation-preserving (DRP) scheme finite difference method, time item then use total variation diminishing (TVD) Runge-Kutta method format, thereby to achieve the accuracy of its value, the paper also use topological theory to analyze the characteristics of singularity, and draw a three-dimensional flow field pattern thereby to observe the structure and flow of the flow field case, with the result that the Reynolds number increased flow into the spiral point position will gradually close the bottom of the cavity, and with the impact of an increase in the Reynolds number at the bottom of the singular point significantly smaller
