Abstract:

Shallow-fluid equation models have been applied to several Army problem areas, especially those associated with atmospheric transport and diffusion. The objective of this report is to present the development of a system of equations which govern the behavior of material atmospheric layers and which retain the advantages of the shallow-fluid equations but are more generally suitable for atmospheric analysis. The report consists of three major sections. The first section presents a formal derivation of what therein is defined as the Material Layer Equations. The second section addresses some of the practical considerations involved in applications of the material layer equations. Although the presentation of numerical algorithms for specific applications of the material layer equations is beyond the scope of this report, the third section does present elementary examples of how the material layer equations may be specialized to address specific atmospheric analysis problems. It is concluded that the material layer approach is most useful when the matter of concern is the transport and diffusion of material such as from NBC weapons or smoke. Author
