Abstract

In the foregoing chapter, we encountered boundaries of solid bodies and obstacles that are fully covered by streamlines of the flow. There is no necessity that one single streamline follows the whole boundary of an obstacle. Instead, the streamline can detach from the solid body; it is then called a free streamline. Three standard flow scenarios with free streamlines are jets, wakes, and cavities, shown schematically in Fig. 5.1. The subsequent Figs. 5.2, 5.3, and 5.4 show examples of these flow types. From a theoretical perspective, the interest in free streamlines lies in the fact that they pose boundary value problems where the shape of the boundary is not known aforehand but has to be determined as part of the solution of the problem. This is also true for free surface waves, which are the subject of Chap.  8.
