    En este art´?culo introducimos un concepto basado en el m´etodo diferencial de restriccionespara examinar el procedimiento de clausura en Modelos de Turbulencia.Mostramos como este concepto puede ser aplicado para estudiar el problema de interacci´on y mexclado entre dos campos de flujo turbulento homog´eneo semi-infinito dediferentes escalas.Palabras clave:  Modelos de turbulencia, procedimiento de clausura, restricciones diferenciales,conjuntos invariantes, modelo de clausura de tercer orden, soluci´on autosimilar,comportamiento asint´otico.

    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.
