A General Analysis of Free Turbulent Mixing

Abstract

A general analysis applicable to a variety of free mixing flows of engineering interest is described. An empirical relationship between the turbulent shear stress and the turbulent kinetic energy is used. Algebraic relationships are used to obtain the length scales required to close the turbulent kinetic energy equation. The computer program developed to provide the numerical framework for this analysis is described, and a FORTRAN listing and description of required inputs is included. To demonstrate the capabilities of the analysis, a number of experimental free mixing flows have been calculated, and the results of these calculations are discussed.
