Abstract: Abstract This chapter illustrates the principles of computing potential flows in unbounded fluid (without a free surface). It applies a strongly simplified source-sink method to the non-lifting flow around a body of arbitrary shape, and the steady lifting flow around an airfoil, both in two space dimensions. In the latter example, the patch method is explained: a variant of the usual panel method, which aims for both simpler formula and better accuracy of the pressure force.
