Relation of the Statistical Theory of Turbulence to Hydraulics

Abstract

The basic principles of the statistical theory of fluid turbulence are outlined in this paper. Only those ideas and conceptions of importance in hydraulics problems are presented; the more complicated mathematical details are omitted. Turbulence can be characterized by intensity parameters which are the root mean square values of the fluctuating velocity components, and a length parameter proportional to the most probable eddy size.
