ABSTRACT

This chapter explores some of the results that may be deduced about the nature of a ¡owing continuum without reference to the dynamics of the continuum.

The ‡rst topic, ¡ow lines, introduces the notions of streamlines, pathlines, and streaklines. These concepts not only are useful for ¡ow-visualization experiments but also supply the means by which solutions to the governing equations may be interpreted physically.
