ABSTRACT
The discussion given in the preceding chapters has mainly been concerned with onedimensional flows. This is because a large number of flows that occur in engineering practice can be adequately modeled, at least for preliminary design purposes, by assuming that the flow is one-dimensional and because an understanding of many features of compressible flows can be gained by considering one-dimensional flow. However, this assumption is not always adequate. There are a number of flows in which it is necessary to account for the two-or three-dimensional nature of the flow. For example, the flows shown in Figure 14.1 cannot be treated as one-dimensional.
