    Eddy structure in turbulent boundary layers. Author links open overlay (linear) rapid distortion theory, and both laboratory and field experimental data. The large-scale eddy structure near the wall in boundary layers is distorted in several ways: by the strong mean shear, by the blocking of the normal velocity component and by the moving Cited by:   After a discussion of the basic concepts, mathematical tools and methods for closure, the book considers second order closure models. Emphasis is placed upon this approach because it embodies potentials for clarifying numerous problems in turbulent shear flows.

The thrust of this paper is to validate, test and compare several Coherent Structure eduction methods utilizing the same data base. The flow chosen was that of an experimental study of a plane, incompressible, fully developed turbulent two-stream mixing layer.

The mixing layer was chosen as the data base because it has been studied extensively from a coherent structures point of by:   Structure of Turbulent Shear Flows: A New Look.

Turbulent flow is a most important branch of fluid dynamics yet its complexity has tended to make it one of the least understood. Empirical data have been appearing rapidly for more than twenty years but a consistent theory of turbulent flow based on the results has been lacking.

The original edition of Dr Townsend's book was the first to attempt a systematic and comprehensive discussion of 5/5(1). Townsend (The Structure of Turbulent Shear Flow,Cambridge University Press) proposed a structural model for the logarithmic layer (log layer) of wall turbulence at high Reynolds numbers.

Structure of turbulent shear flows. Radial and axial profiles of the flowfield were made in isothermal and combusting flows. The free-jet behavior is that anticipated from other studies. Turbulent eddies near a wall Flow structure A rigid plane boundary, or ‘wall’, affects any turbulent velocity field generated above it through several mechanisms.

Figure 1 shows a schematic of the high-Reynolds-number boundary layer with freestream velocity, U E. This eddy structure matches that observed in simulations of homogeneous-shear flows and channel flows by several workers and also fits with earlier field and wind-tunnel measurements in canopy flows.

Large eddy simula-tion greatly reduces the amount of empiricism in the physical modeling, but is sensitive to a number of numerical issues. This paper includes an overview of the importance of Modeling of Turbulent Free Shear Flows .In this paper we address this problem by proposing several novel approaches for more accurately segmenting individual eddy structures in turbulent flows.
