Some Key Concepts in Nonstandard Analysis Theory of Turbulence

Some important concepts in the nonstandard analysis theory of turbulence are presented. The point structure, on which differential equations are defined, is analysed. The distinction between the uniform point and the non-uniform point, as well as between the standard point and the nonstandard point, is shown. A new kind of equations, which differ essentially from those in existent theory, is emphasized. These new equations can hold at non-uniform points. The applicability of the Navier--Stokes equations to turbulence is discussed. Some illustrations of the nonstandard analysis theory of turbulence are also presented.
