Streamlines and stream function [Aerodynamics #6]

In this lecture, we discuss methods for visualizing a flow field and develop tools to better diagnose flows. Pathlines, streaklines, and streamlines are all different ways to visualize a flow, yet in a steady flow they're all the same. We mathematically define streamlines in detail, then build a new "stream function" that defines the set of streamlines based upon the velocity field.
