By Peter A. Davidson, Yukio Kaneda, Keith Moffatt, Katepalli R. Sreenivasan

Turbulence is widely known as one of many awesome difficulties of the actual sciences, however it nonetheless is still basically in part understood regardless of having attracted the sustained efforts of many major scientists for good over a century. In A Voyage via Turbulence we're transported via a very important interval of the background of the topic through biographies of twelve of its nice personalities, beginning with Osborne Reynolds and his pioneering paintings of the Eighteen Eighties. This ebook will offer soaking up analyzing for each scientist, mathematician and engineer drawn to the background and tradition of turbulence, as heritage to the serious demanding situations that this common phenomenon nonetheless offers.

In view of the subject of this book, the present account (which draws extensively from an earlier paper by the authors: Jackson and Launder, 2007) focuses particularly on his two major papers on turbulent flows (Reynolds, 1883; Reynolds, 1895), although this was by no means the only subject on which he was working at that time. While our principal attention will be focused on the later analytical study, Reynolds (1895), we first consider the experimental investigation, Reynolds (1883), as the discoveries in that paper shaped the later publication and, moreover, had made a significant impression on one referee who was called upon to review each of the papers.

For some of these studies he contrived simple but effective small-scale experiments using relatively unsophisticated apparatus. Even after the removal of the College in 1873 to a new purposebuilt campus on a site south of the city centre (today the core of Manchester University) there was initially only limited scope for experimental work. A fuller summary of this phase of Reynolds’ research appears in Jackson (1995) together with reproductions of the diagrams of the apparatus used in each case.

It would seem as if there had been a slip in writing u for u; but at any rate there is need of explanation. It is to be noted that the argument, if valid, would show that there are geometrical difficulties in the way of applying the idea of mean velocity to cases other than steady homogeneous motion. The essence of the paper lies in the equations on pp. 15,162 . If these are clearly established a great point would be secured, but its reasoning is somewhat obscure, and needs much amplification. The conception of ‘mean-mean-motion’ is a very delicate one and it is not made evident in what sense u, v, w are continuous functions, or on what conditions the derivatives, etc.
