Turbule Ensemble Model of Atmospheric Turbulence: Progress in its Development and Use in Acoustical-Scattering Investigations
Abstract
The objective of one portion of the Army Research Laboratory program on acoustic propagation on the battlefield is to develop an advanced method of accounting for the effects of anisotropic inhomogeneous turbulence. The approach chosen was to extend the idea of eddies under the assumption that the turbulence field is made up of a multiplicity of isolated eddies of different sizes. This method of describing turbulence is called the Turbule Ensemble Model (TEM). A turbule is defined to be a localized inhomogeneity of any type. The primary types are temperature and velocity inhomogeneities; the term turbule is an extension of the idea of an eddy, which is normally associated with a velocity disturbance. In the TEM, then, the turbulent region is populated with a collection of turbules of different sizes and types with the locations of the turbules chosen according to some rule. Since the program began in 1992, a number of publications have been generated that have dealt with the details of creating and using the TEM concept. This report contains information on these reports including author, title, where copies may be obtained, date, and a brief description.
