Abstract:

The problem of the analysis of free turbulent mixing is complex, and some empiricism is always necessary to obtain a solution. This has led to a proliferation of experiments and of semi-empirical models for the turbulent shear stress. All of these models will correlate experimental data well in some region of a particular flow, but not in others. The ultimate goal of the study is to confront each important model for the turbulent shear stress with as broad a range of experimental data as possible. From this confrontation come two sets of conclusions--one detailing those models presently suitable for engineering use, and the second establishing the models which show promise of becoming more generally applicable with further development.
