On the problem of turbulence

Abstract
A central theme in the history of the turbulence problem is about the method of 'closure' in the models and 'theories' which have been proposed. Closure has invariably been by empirical calibration with experimental data. In this note we draw attention to a paper by Morris, Giridharan and Lilley, in which for the first time empiricism is obviated. For the turbulent mixing layer, this is accomplished by including in its description the mechanism for production of turbulent shear stress (i.e. turbulent momentum transfer), by large-scale instability waves. Some implications for the theory of turbulent shear flows are discussed.
Additional Information
This article is dedicated to Satish Dhawan on his eightieth birthday. I have long admired him for his contributions and dedication to science, teaching, technology, statesmanship and humanity. This article is not a review and explicit references are not provided except for the paper on which the discussion is focused. During the last quarter century many investigators have made significant contributions to the ideas that have developed toward that focus. This writing has benefited from many discussions with J. E. Broadwell.Attached Files
