This is the simplest of the elementary potential flows. We will start with an arbitrary freestream velocity, derive the velocity potential, and then verify the original velocity. Using the Cartesian velocity X and Y components, we will code up a simple script for the flow-field in a uniform flow, and compute the circulation around an arbitrary curve.
