Investigation of Self-Preservation Theory in Two Dimensional Turbulent Mixing Layers
A. Shabani, H. Basirat Tabrizi
Abstract
The behavior of a two dimensional, steady turbulent mixing layer was investigated. Besides the usual velocity components, all the contributing components of the Reynolds Stresses are also calculated and presented. The results indicated that in the two dimensional steady turbulent mixing layers the theory of self-preservation is not valid for all the flow domain, and that the flow is turbulent regime is divided into two areas. Through calculation of Reynolds Stress components at the point of initiation of the flow, it was shown that the turbulent flow in the area containing the point of singularity of the flow is not, as previously believed, self-preserved.
