A method for analyzing turbulence models

In this article we introduce a concept based on the differential constraints methodto examine the closure procedure in Turbulence Models. We show how this conceptmay be applied to study the problem of interaction and mixing between two semiinfinitehomogeneous turbulent flow fields of different scale...

Sumario: In this article we introduce a concept based on the differential constraints methodto examine the closure procedure in Turbulence Models. We show how this conceptmay be applied to study the problem of interaction and mixing between two semiinfinitehomogeneous turbulent flow fields of different scales.Keywords:  ResumenTurbulence models, closure procedure, differential constraints, invariant sets,third-order closure model, selfsimilar solution, asymptotic behavior.
