Here, we derive, non-dimensionalize, and solve partial differential equations. We ask not just "what is the drag force?" but "will the boundary layer separate?" or "is the flow linearly stable?" advanced fluid mechanics problems and solutions
Specifically: Show that a necessary condition for the existence of an exponentially growing normal mode disturbance is that ( U''(y) ) changes sign somewhere in the flow (i.e., ( U(y) ) has an inflection point). Drop it in the comments below
