Irrotational flows of a viscous fluid satisfy the Navier-Stokes equations. These flows depend on the Reynolds number R_e and reduce to inviscid potential flow when the Reynolds number is infinite. The papers in this collection show that potential flow at a finite Reynolds number is a rich theory which yields excellent physical results in selected cases. When considering potential flow it is neither necessary nor useful to put the viscosity to zero. The theory of irrotational flow of a viscoelastic fluid is also a valuable and useful theory for linear viscoelastic fluids, second order fluids and special solutions of more general models.
