This chapter discusses potential flow, which is used to determine basic properties of hydrofoils and lifting wings. That includes keels, rudders, and propellers. It is also employed in the prediction of cavitation inception and in seakeeping. Before studying the equations that allow us to actually compute a potential, the chapter explores the somewhat confusing connection between circulation and velocity potential. Velocity potentials are a powerful tool for the description of a large class of flows, so‐called potential flows. The application of the conservation of mass and conservation of momentum principles for Newtonian fluids led us to the continuity equation and Navier‐Stokes equations. The Laplace equation forms the basis of potential theory. The chapter explains that the physical principles of conservation of mass and momentum are cast into the Laplace equation and Bernoulli equation for potential flow.
