Lecture
This lecture covers the computation of forces exerted by a flow on solid objects, focusing on lift and drag calculations for incompressible, inviscid, and irrotational flows. It discusses the concept of potential flow, superposition of basic flows, and the use of velocity potential and stream function. The lecture also explores the application of potential flow theory to analyze flow around 2D bodies, including airfoils and rotating cylinders. The presentation concludes with the discussion of stagnation points, the Magnus effect, and the superposition of basic flows to represent flow around bodies.
