ABSTRACT

In the previous chapter we began looking at the nature of ideal motions of fluids and, in particular, the kinetic concepts arising from the fact that in such motions pressures are the dominant surface forces acting on a fluid element. There are also kinematic concepts that apply to ideal flows, and the mathematical relationships that result from these are particularly useful in the analysis of such flows. In this chapter we examine these kinematic aspects, which, in combination with the stream function, provide the fundamental tools and methods commonly used in the analysis of ideal fluid flows.
