2D Potential Flows

This lecture covers the concept of 2D potential flows in fluid dynamics, focusing on the relationship between stream function and velocity potential. The instructor explains the assumptions made for incompressible, inviscid, and irrotational flows in a 2D scenario. The lecture delves into the Laplacian equations satisfied by the velocity potential and stream function, highlighting their connection and differences. Additionally, the lecture demonstrates how to visualize flows using streamlines and equipotential lines, emphasizing their perpendicular relationship. Through an example calculation, the instructor illustrates how to determine the stream function from a given velocity potential, showcasing the process of integrating partial derivatives to derive the stream function.
