Chapter 9, Problem 54P

Flow separates at a shap corner along a wall and froms a recirculating and a recirculating separtion bubble as sketched in Fig. 9-54 (streamlines are shown). The value of the stream function at the wall is zero, and that of the uppermost streamline is positive value ${\psi }_{\text{upper}}$ . Diccuss the value of the stream function inside the separetion bubble. In particular, is it positive or negative? Why? Where in the flow is $\psi$a minimun?
