Structures and their evolution in the turbulent shear layer
Abstract
Two turbulent shear layer models, formulated as linear chains of vortex structures that merge in pairs, are used to obtain selfsimilar relationships between the basic shearlayer parameters. The form of the structures, determined by statistical mechanics, coincides with that for statistical equilibrium for the simplest model. The nondimensional intermittence parameter is calculated with a relative precision of 0.14 using the totalenergy conservation law. The effect of angularmomentum conservation on various shear layer parameters is demonstrated. A more realistic shearlayer model is formulated as a linear chain of similarly oriented clusters consisting of several statistically equilibrium substructures. The minimum and maximum number of cluster substructures occurring during the evolution process are also required.
