dc.description.abstract | **Please note that the full text is embargoed** ABSTRACT: A turbulence model that describes dynamics of large,
characteristic eddies in inhomogeneous flows is proposed; two
closure parameters are initially undetermined. To determine the
optimum values of these parameters, the present model is
applied to channel flows at two Reynolds numbers. The nature of
the closure parameters and their effects upon predicted
Reynolds stresses and other turbulence structural quantities
are examined and optimum values are suggested. It is
demonstrated that the current Large-Eddy Interaction Model not
only predicts Reynolds stresses reasonably but also presents an
opportunity to illuminate typical characteristic motions of
large-scale turbulence and the phenomenological aspects of
engineering models for the two Reynolds numbers investigated.
In addition, analysis of the spatial correlation integral
suggests that a strange attractor found in the fully-developed
channel flow has a low fractal dimension. | en |
